This study investigates the correlation between coercivity (Hc), grain size (d), and dislocation density in the Permimphy alloy (Fe–80%Ni–6%Mo). The samples used in this study were subjected to varying levels of applied strain through processing by high-pressure torsion. The microstructure and the magnetic coercivity were analyzed using a scanning electron microscope, electron backscatter diffraction and vibrating sample magnetometry. The grain size of the samples varied from 30 to 190 nm. This study demonstrated a strong correlation between Hc and microhardness when d > 3 µm. The results show that the coercivity of the Permimphy alloy follows an inverse V-shape with respect to grain size. The coercivity of the samples decreased despite increasing the dislocation density and the hardness when d < 3 µm. This phenomenon is attributed to the ferromagnetic exchange interaction across multiple grains and leads to the alignment of magnetic moments. [ABSTRACT FROM AUTHOR]

Soft magnetic materials (SMMs) are extensively used in various fields such as power generation, energy transfer and electromagnetic interference damping. The preparation of SMMs in different forms requires expertise in diverse fabrication techniques. Furthermore, achieving optimal performance requires an understanding of the relationship between magnetic behavior and microstructure and mechanical properties of SMMs. This study focuses on analyzing the effects of accumulative roll-bonding (ARB) processing on the texture, microstructure, and magnetic properties of a commercial Permimphy alloy (Fe–80Ni–5Mo wt%). Electron BackScattered Diffraction (EBSD) analysis confirmed the expected refinement of the grain structure resulting from ARB processing, leading to a reduction in the transverse dimension of the elongated grain down to 800 nm after five cycles. The microhardness of the alloy increased by 80% compared to the as-received sample, primarily due to the refinement of the microstructure and the formation of a high density of dislocations. The findings suggest that the magnetic domain walls are more affected by low-angle boundaries rather than grain/high-angle boundaries. In addition, it was proved that subsequent annealing at 550 °C for one hour improved the alloy's magnetic softness while maintaining the mechanical hardness achieved through ARB deformation. This improvement was attributed mainly to the removal of stresses and defects in the material without initiating the process of recrystallization. [ABSTRACT FROM AUTHOR]

High‐pressure torsion (HPT) processing is successfully applied to fabricate a novel hybrid material from separate discs of AZ31 (Mg–3Al–1Zn, wt%) and Mg–0.6Gd (wt%) alloys by straining through numbers of rotations, N, of 1/4, 1/2, 5, 10, and 20 turns at room temperature. The microstructure and texture are investigated near the bonding interface through the disc diameter using electron backscatter diffraction (EBSD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The microstructure exhibits two grain refinement regimes with the first occurring during an equivalent strain range, εeq, of ≈0.3–72 and the second during εeq from ≈72 to 517. The general texture changes from B‐fiber to Y‐fiber and C2‐fiber through the HPT processing. The resultant microstructures and textures of this hybrid alloy are examined separately for the AZ31 and Mg‐0.6Gd alloys and found controlled by the presence of twinning, slip systems, and second phases and the occurrence of different dynamic recrystallization mechanisms.

The local microstructure, texture gradient and mechanical properties through the shoulder dimension (10 mm) of upper and lower AA5182 aluminum sheets were investigated using electron backscatter diffraction (EBSD) and Vickers microhardness after friction stir spot welding (FSSW). Based on the microstructural features (mean grain size, grain boundary type and dynamic recrystallization (DRX)), the upper sheet was found to be mainly composed of the stir zone (SZ) and thermomechanically affected zone (TMAZ) due to the high deformation induced simultaneously by the tool rotation and the shoulder download force, while the SZ, TMAZ, heat-affected zone (HAZ) and base metal (BM) were detected in the lower sheet due to the limited effect of the shoulder on the lower sheet. The texture changes, due to the nature of the deformation, demonstrated a shear-type texture at the SZ to a plane strain compression deformation type texture at the TMAZ and then a recrystallization texture at the HAZ and BM. The microhardness gradually decreased with the increasing distance from the keyhole along the SZ, TMAZ and HAZ regions. Eventually, the microstructure and microhardness evolutions were correlated based on the Hall–Petch relationship. [ABSTRACT FROM AUTHOR]

A Fe-48wt%Ni alloy was processed by severe plastic deformation using equal channel angular pressing process. A stacking of 9 sheets was introduced and pressed up to two passes into die with an inner angle of Φ = 90º and outer arc of curvature ψ = 17° at room temperature following route A. The same material in bulk form was also ECAPed up to one pass. The microstructure and the texture were investigated by means of electron backscattered diffraction and X-ray diffraction, respectively. To evaluate the mechanical response, Vickers microhardness was carried out. The given analyses concern the as-received sample, the peripheral and the central plates of the pressed stacks and the upper, the middle and the lower parts of the pressed bulk material. The deformation was heterogeneous, and variations in texture and microstructure, resulting from different efficiencies in the shearing process, were locally noted. For the stacks samples, the microstructure evolved from equiaxed grains of 9 μm with high fraction of high-angle grain boundaries (around 90%) to a heterogeneous fine grain structure with an average grain size of 3 μm after two passes. On the contrary, for the bulk sample, the evolution was to a banded structure after one pass. Results of mechanical property show that microhardness increased significantly from 147 Hv before deformation to mean values of 244 (after one pass) and 235 Hv (after two passes) for the bulk and stacked samples, respectively. The Hall-Petch effect and dislocation density were evaluated as most responsible in material strengthening. [ABSTRACT FROM AUTHOR]

Microstructure and texture evolution of Fe-36%Ni (wt. %) alloy after 1, 5 and 10 accumulative roll-bonding (ARB) cycles and annealing at 600 °C up to 3600 seconds were studied using electron backscatter diffraction. Microstructural and textural changes after ARB and annealing were compared to those existing in the literature after conventional rolling. The microstructure was not stable at 600 °C for all ARB samples even after 3600 seconds of annealing. The recrystallization texture was dominated by the Cube {001}<100> texture component. Recrystallization kinetics were determined using microhardness measurement and were close to those after cold rolling with Avrami time exponent around unity. The texture evolution at high strain was discussed in terms of grain boundary migration obstruction by the formation of layer interfaces and small recrystallized grains near the bonded interfaces.

The evolution of microstructure and texture during friction stir lap welding (FSLW) of TIMETAL 21S (β-type Ti-15Mo-3Nb-3Al-0.2Si, wt%) sheets were investigated through electron backscatter diffraction (EBSD). Excellent grain refinement is obtained through stir zone (SZ) thickness (1.2–1.8 μm). The microstructure of the thermomechanically affected zone (TMAZ) is characterized by elongated deformed grains surrounded by small recrystallized grains indicating the occurrence of discontinuous dynamic recrystallization (DDRX). The microstructure of heat affected zone (HAZ) is quite similar to the base metal (BM). The texture transformed from weak rolling-recrystallization texture in BM and HAZ to a typical shear texture with the domination of D 1 or D 2 components in the SZ and TMAZ area. A net shear texture gradient is formed across the SZ thickness which is connected with the heterogeneity of deformation. It is believed that the concomitant occurrence of grain size, dislocation and texture strengthening is responsible for the mechanical property distribution in different parts of FSLW joint. • TIMETAL 21S sheets were successfully fabricated by FSLW. • Excellent grain refinement (1.2–1.8 μm) was obtained in SZ during the FSLW. • A net shear texture gradient is developed across the thickness of SZ. • The microstructure evolution of TMAZ indicates the occurrence of DDRX. • The microstructure and texture of HAZ are quite similar to those of BM.

The evolution of microstructure, texture, and mechanical properties of an Mg–1.43Nd (wt%) alloy is investigated after processing by high‐pressure torsion at room temperature through five turns and isochronal annealing for 1 h at 150, 250, 350, and 450 °C using electron backscatter diffraction and Vickers microhardness. The alloy exhibits a good thermal stability up to annealing at 250 °C, with mean grain size of ≈0.65 μm. The microhardness shows an initial hardening after annealing at 150 °C and then a subsequent softening. The deformation texture, a basal texture shifted 60° away from the shear direction (SD), is retained during annealing up to 250 °C. In contrast, a basal texture with symmetrical splitting toward SD is developed after annealing at 350 °C. The precipitation sequence and their pinning effects are responsible for the age‐hardening, stabilization of grain size, and the texture modification. The kinetics of grain growth in the Mg–1.43Nd alloy follows two stages depending on the temperature annealing range, with an activation energy of ≈26 kJ mol−1 in the low temperature range of 150–250 °C and ≈147 kJ mol−1 in the high temperature range of 250–450 °C.

The stored energy, which is the main driving energy of the primary recrystallization, was measured in two Fe–48%Ni cold-rolled samples using three different approaches: the neutron diffraction method based on the peak broadening, the Kernel Average misorientation (KAM) and the Dillamore methods both based on the misorientation and dislocation cell size estimation using EBSD (Electron Back Scatter Diffraction) data. The results were compared with each other and showed differences in stored energy values. In this paper, it is demonstrated that the stored energy calculated by both KAM and Dillamore approaches is underestimated compared to that one calculated from neutron diffraction peak broadening. This is because Dillamore approach considers only the GND (Geometrically Necessary Dislocations), blocked in the cell walls, the KAM method takes into account only the GND in all of the microstructure (cells and walls) and the neutron diffraction method takes into consideration all types of dislocations (SSD (Statistically Stored Dislocations) and GND) within the microstructure. The measurement principle and the energy gap observed between the different approaches were discussed. [ABSTRACT FROM AUTHOR]

Abstract: The Armco iron is one of the purest commercial iron with very low levels of carbon, oxygen and nitrogen. In order to improve the mechanical properties, it is worth applying severe plastic deformation to obtain ultrafine-grained bulk materials, with grain size <1μm. In this study, samples of Armco iron were subjected to a technique of severe plastic deformation named Accumulative Roll Bonding. The important parameter of this process is the number of passes and the deduced von Mises equivalent strain. By means of the Electron BackScattered Diffraction and X-Ray diffraction, the evolution of microstructure and texture with the applied strain was studied. The microhardness was also measured as a function of the equivalent strain and reached 280 HV after 7 ARB cycles. The ARB technique applied to Armco iron resulted in a microstructure of ultrafine grains of about 580nm after 7 cycles, with a high angle grain boundary fraction of 60%. The texture is mainly composed of α and γ fibers with a reinforcement of both {001}〈110〉 and {111}〈110〉 components. [Copyright &y& Elsevier]

Transparent polycrystalline ZnGa 2 O 4 ceramics are synthesized, for the first time, by combining high-energy ball milling, solid-state reaction and spark plasma sintering. They appear transparent in both the visible and near infrared (up to 9 μm) ranges after a post-SPS annealing in air converting the raw semiconductor into an electrical insulator. The maximum of transmittance is reached in the near infrared region, at around 2.5 μm, with a value of 78 % (1 mm thick sample) close to the maximum value of transmittance previously measured for single crystals. These transparent ceramics present a classic cubic spinel ZnGa 2 O 4 structure and a dense microstructure (> 99 %) attained without sintering aids, with an average grain size of 600 nm and a random orientation of the crystallites. TEM observations performed on thin foils have revealed limited nanometer scale intergranular porosity which does not affect much the transparency. As a proof of interest, red long-lasting luminescence arising from the entire sample volume is observed in these Cr3+ doped transparent ceramics. This innovative work is anticipated to further drive the development of transparent ZnGa 2 O 4 ceramics towards a wider range of performing optical applications such as laser emission.

Abstract Samples of an Mg-0.41Dy (wt. %) alloy were severely deformed by high-pressure torsion (HPT) at room temperature up to 15 turns and the texture, microstructure and microhardness values in the centres, mid-radial points and edges of the HPT-deformed discs were investigated using X-ray diffraction, Electron BackScatter Diffraction and Vickers microhardness measurements. The textures in the centres of discs were characterized by a typical weak basal fiber whereas at both the mid-points and edges of the discs there was a strong basal texture where the c-axis of most grains was shifted 15° away from the shear direction. An almost homogeneous ultrafine-grained structure with a grain size of about 0.75 μm was achieved after 15 HPT turns. The microhardness values in these three positions increased with increasing numbers of turns, reached a maximum and then decreased to a lower steady-state level at large strains. In addition to dislocation and grain size hardening, the results show that texture strengthening contributes significantly to the rapid increase in hardening in the early stages of deformation. Highlights • A basal fiber texture is developed with some differences between the centre to edge. • A significant grain refinement to ∼0.75 μm was evident after HPT processing. • The microstructure after 15 HPT turns contained about 77% of recrystallized grains. • Texture strengthening makes a contribution to the rapid increase in hardening.

Abstract The microstructure and texture of an Al1050/AZ31/Al1050 laminated composite fabricated by accumulative roll bonding at 400 °C up to 5 cycles are investigated using Electron BackScatter Diffraction, neutron diffraction, microhardness measurements and tensile tests. EBSD analysis has shown that ARB processing led to microstructural refinement with equiaxed grain microstructure in AZ31 layers and to the development of elongated grains parallel to the rolling direction in Al 1050 layers. No new phases formed at the bond interface after the first ARB cycle while Mg 17 Al 12 and Mg 2 Al 3 phases appeared after subsequent cycles. During the ARB processing, a typical strong basal (0002) texture is observed in AZ31 layers along with a weak rolling texture showed in Al 1050 layers with a dominant Rotated Cube {001}〈110〉 component. The microhardness of Al1050/AZ31/Al1050 laminated composite increased with increasing ARB cycles and almost saturated after five ARB cycles. The yield strength and ultimate strength increased gradually between 1 and 3 ARB cycles due to the strain hardening and grain refinement. They decreased with further increasing of the ARB cycles because of crack and failure of the Mg x Al y intermetallic compounds which developed during 4th and 5th ARB cycles. The deformation behavior of the laminated composite becomes rather similar to the behavior of AZ31 alloy that underwent a dynamic recrystallization during processing. Highlights • Formation of Mg 17 Al 12 and Mg 2 Al 3 phases was obtained near the interface after 2 ARB cycle. • The average grain size of AZ31 layers was about 0.8 μm after 5 ARB cycles. • The Al 1050 layers contain elongated grains parallel to rolling direction. • A typical strong basal (0002) texture has been observed in AZ31 layer. • A weak rolling texture showed in Al 1050 layer with domination of Rotated Cube.

Abstract The optimization of the microstructure of the UC x target is a key point since many years in the field of ISOL method. The ultimate goal is to facilitate the release of the fission products, especially those with short half-lives. Fourteen UC x samples were synthetized from different uranium and carbon sources using three mixing protocols. All carburized samples were systematically characterized in terms of nature and proportion phases, grain and aggregate size, open and close porosity proportion and open pore size distribution. Our results were analysed using a multivariate statistical approach in order to remove any subjective bias. Strong correlations between the physicochemical characteristics of the samples as well as the impact of the synthesis process have been highlighted. In particular, using carbon nanotubes as carbon source combined with a new method of mixing is the key parameter to limit the sintering and to obtain samples with small grains and a high porosity well distributed over small pores. Moreover the microstructure obtained proved to be stable at high temperature. [ABSTRACT FROM AUTHOR]

Electron backscatter diffraction (EBSD) was used to evaluate the evolution of microstructure and texture in an Fe-36%Ni (wt. %) alloy after processing by high-pressure torsion (HPT) up to 10 turns at ambient temperature and 250 °C. HPT processing led to a strong microstructural refinement with average grain sizes of ∼0.30 and ∼0.24 μm at ambient temperature and 250 °C, respectively. The high-angle grain boundary fraction was slightly higher after processing at 250 °C and gradually increased with increasing numbers of HPT turns to saturate after 5 turns. The crystallographic texture after HPT processing at ambient temperature was characterized by typical A and B fibers of a simple shear FCC texture with domination of the B component. By contrast, the A , B and C components developed during HPT processing at 250 °C with C as the dominant texture component. The microhardness values for both HPT deformation conditions were very similar with a continuous increase with increasing HPT turns and almost saturation after 5 HPT turns. The grain size dependence of the microhardness followed the Hall-Petch relationship. The explanation for the microstructure, texture and microhardness difference was attributed to a dynamic recovery process that operates during processing at 250 °C. [ABSTRACT FROM AUTHOR]

We have studied the development of intrinsic stress and microstructure of copper (Cu) films deposited under energetic ion bombardment. Stress evolution during growth of ∼150 nm thick Cu films on Si(001) substrates has been investigated by in situ measurements in a high power impulse magnetron sputtering (HiPIMS) process for different substrate bias voltages (from 0 to −160 V) and benchmarked with conventional direct current magnetron sputtering (DCMS). The microstructure and crystal orientation of the studied films have been examined by various ex situ methods. For HiPIMS, we found that the substrate bias voltage (energy of Cu ions) strongly affects the film continuity during the early growth stages and the compressive stress developed during the post-coalescence stage. Contrarily to common expectations, the stress magnitude can be significantly reduced despite the energy increase of the bombarding particles when using HiPIMS. These results are discussed based on a recent kinetic model taking into account the grain size-dependent defect incorporation due to energetic particle bombardment. Reversible stress relaxations are observed upon growth interrupts, with characteristic time constants of tens of seconds, which suggests that the stress and microstructure development are mainly mediated by surface diffusion processes. In addition, polycrystalline films (111)-textured are obtained for negative bias voltages from 0 to −100 V, while for even higher negative bias voltages (up to −160 V), epitaxial growth of Cu(001) is achieved. For the DCMS samples, there is no significant change in film continuity and crystal orientation when varying the bias voltage. [ABSTRACT FROM AUTHOR]

The development of generation IV nuclear reactor requires improvements in structural and cladding materials. Oxide dispersion strengthened (ODS) steels are promising candidates because of improved creep properties. Two main families of ODS steels are known, the first one is martensitic ODS steel with a full reverse ferrite to austenite phase transformation at high temperatures. The second one is ferritic ODS steels with a ferritic matrix whatever is the temperature. Previous papers mention the existence of untransformed ferrite (UF) phase at high temperature in very particular martensitic ODS steels [S. Ukai 2009, M. Yamamoto 2010, T. Yamashiro 2016, A. Durand 2021]. UF is unexpected according to experimental observation and thermodynamic calculations of the non-strengthened materials (NR) with same chemical composition. This UF is particularly interesting because UF is a way to improve the creep resistance of martensitic grades [H. Sakasegawa 2008, A. Durand 2021] and then conciliates the benefits of both ferritic and martensitic grades. The present study is focused on the thermal stability of untransformed ferrite (UF) in a martensitic ODS steel at 10 wt% Cr. Effects of the heat treatments holding times and temperatures are studied by considering the UF fraction evolution and microstructural changes. The decrease of UF fraction is correlated with the decrease of the nano-oxides density coupled to the increase of their size. The phase transformation temperatures of ODS steels are also affected by heat treatments. Those temperatures appear as a mix of the ODS and the equivalent non-strengthened materials ones.

Thermal stability of a Cu-Cr-Zr alloy processed by equal-channel angular pressing up to16 passes was investigated using isochronal annealing ranging from 250 to 850 °C for 1 h. The microstructure, crystallographic texture and micro hardness of samples were characterized through electron back scatter diffraction and Vickers micro hardness measurements. The recrystallized grain size was stable between 250 °C and 500 °C then increased quickly. The achieved mean grain size, after 1, 4 and 16 ECAP passes, was around 5.5 μm. A discontinuous mode of recrystallization was found to occur and a Particle Simulated Nucleation mechanism was evidenced. The evolution of the high angle grain boundary fraction increased notably after annealing above 550 °C. The crystallographic texture after isochronal annealing was similar to that of ECAP simple shear, no change of the texture during annealing was observed but only slight intensity variations. Micro hardness of all Cu–Cr–Zr samples showed a hardening with two peaks at 400 and 500 °C associated with precipitation of Cu cluster and Cu 5 Zr phase respectively, followed by a subsequent softening upon increasing the annealing temperature due to recrystallization.

Experiments were conducted to evaluate the evolution of microstructure and texture in a commercial Cu–2.5Ni–0.6Si (wt.%) alloy processed by equal-channel angular pressing (ECAP) at 423 K for up to 12 passes. An electron backscatter diffraction (EBSD) analysis shows that ECAP processing leads to microstructural refinement with an average grain size of ∼0.9 μm. The refined grains are inclined to the direction of extrusion and the deformation structure evolves from elongated grains to a duplex microstructure of equiaxed and elongated grains. Detailed measurements demonstrate that the grain boundary misorientations gradually increase with increasing numbers of ECAP passes. The texture was investigated using both EBSD and neutron diffraction. The results show the texture after ECAP is characterized by typical shear components of face-centered cubic metals which deviate from their ideal positions. [ABSTRACT FROM AUTHOR]

Abstract: Experiments were conducted to evaluate the evolution of hardness and microstructure in a commercial Al–0.6% Mg–0.4% Si alloy during processing by high-pressure torsion (HPT). The HPT was conducted under a pressure of 6.0GPa and disks were torsionally strained to a maximum of 20 turns. It is shown that processing by HPT leads to microstructural refinement with an average grain size of ∼250nm and to an increase in hardness up to a saturation value at equivalent strains above ∼100. There is a deviation in the Hall–Petch relationship at grain sizes smaller than ∼500nm and this is consistent with an earlier suggestion that a breakdown may occur if there is an easy movement of the extrinsic dislocations in the non-equilibrium grain boundaries introduced by HPT processing.

Abstract: Experiments were conducted to evaluate the evolution of hardness and microstructure in a commercial aluminum 6061 alloy processed by high-pressure torsion (HPT). The results show that processing by HPT leads to significant grain refinement with an average grain size of ∼450nm at the edge of a disk subjected to torsional straining through 5 turns. Hardness measurements show an increase from ∼80Hv in the solid solution condition to ∼160Hv after HPT where these values correlate well with the equivalent strain applied to the disk. Quantitative measurements show the grain size decreases and the fraction of high-angle grain boundaries increases with increasing strain. [Copyright &y& Elsevier]

The characterization of microstructure and texture development of binary Mg-0.3Ce (wt%) after equal-channel angular pressing (ECAP) processing via route Bc at 300 and 350 °C through 4 passes were investigated using electron backscatter diffraction (EBSD) measurements. The results demonstrated an effective grain refinement from millimeter range to 6.7 and 8.3 μm obtained after 4 passes at 300 and 350 °C, respectively. The grain refinement was obtained through dynamic recrystallization (DRX). At 300 °C, DRX occurred at low strain by twin-induced dynamic recrystallization (TDRX) and particle stimulated nucleation (PSN) mechanism and then converted with increasing strain to sub-grain development (SD) and grain boundary bulging dynamic recrystallization (GBBDRX). Besides, grain growth occurred during processing at 350 °C. The texture development strongly depends on the strain level, deformation temperature and DRX mechanisms. At 300 °C, a typical basal texture with a deviation of 40° towards extrusion direction was formed gradually up to 4 passes while a completely different texture was formed at 350 °C due to the large grain size. • Mg-0.3Ce alloy was processed by ECAP for 4 passes at 300 and 350 °C using route Bc. • Significant grain refinement was obtained after 4 passes due to DRX. • At low strain DRX occurred via TDRX and PSN mechanisms. • With increasing strain, SD and GBDRX mechanisms dominate the DRX processing. • Texture evolution strongly depends on the strain, temperature and DRX mechanisms.

The microstructure and texture evolution of an AZ31 alloy were investigated after hot rolling and subsequent annealing using electron backscatter diffraction (EBSD). First, the alloy was hot-rolled at 350 °C up to low, medium and high strain (20, 50 and 85% of thickness reduction, respectively). The alloy samples where then annealed at 350 °C for 2, 10 and 60 min. The effect of strain level and annealing on corrosion behavior in seawater was also evaluated using electrochemical tests. At low strain, the microstructure was characterised by the absence of twinning, mainly due to the prior thermo-mechanical history of the as-received alloy. However, various modes of twinning were observed at medium strain. At high strain, the dynamic recrystallization process resulted in a microstructure with a typical basal texture. The results demonstrate that twins are responsible for the deviation of {0002} basal poles from normal towards the transversal direction. Annealing at 350 °C for up to 60 min led to normal grain growth in all the samples. In medium and highly strained samples, the deformation texture was retained, while the low strain sample underwent noticeable changes due to the absence of dynamic recrystallization. A synergetic effect of grain refinement and texture weakening was responsible for the alloy's enhanced corrosion resistance. • Twins and DRX strongly affected the deformation texture of the hot-rolled AZ31 alloy. • Annealing at 350 °C up to 60 min led to normal grain growth. • Grain refinement and texture weakening was responsible for the corrosion resistance enhancement.
