Abstract

Методами рентгеноструктурного анализа и просвечивающей электронной микроскопии выявлены особенности фазовых и структурных превращений, развивающихся в зонах пластической деформации и разрушения при циклическом нагружении в метастабильной стали 05Г20С2. Определена зависимость фазового состава стали на поверхности усталостного излома от размаха коэффициента интенсивности напряжений в вершине усталостной трещины. The methods of X‑ray diffraction analysis and transmission electron microscopy revealed the features of phase and microstructural transformations developing in plastic deformation and fracture zones of metastable Fe‑20Mn‑2Si steel. The dependence of steel’s phase composition on the fatigue fracture surface on the range of stress intensity coefficient values at the fatigue crack tip is determined.

12. Rheological Properties and Microstructure of AlSi10Mg Aluminum Alloy produced by Selective Laser Melting

Author

Salikhyanov, D. R., Gladkovskii, S. V., Avraamov, Yu. A., Volkov, V. P., Veselova, V. E., Salikhyanov, D. R., Gladkovskii, S. V., Avraamov, Yu. A., Volkov, V. P., and Veselova, V. E.

Abstract

The present study is focused on rheological properties of AlSi10Mg aluminium alloy produced by selective laser melting (SLM) at temperatures of hot deformation with the aim to investigate the dependence of strain resistance on temperature, strain rate and strain degree. As-build cylindrical specimens made of AlSi10Mg aluminium alloy was examined on a cam plastometer in temperature range 20 - 500 °C, at strain rate ξ equal to 1, 10 s-1 up to strain degree e equal to 1.2. The paper presents results of study of initial microstructure, microhardness measurement and flow curves of AlSi10Mg alloy produced by SLM. The flow curves of AlSi10Mg alloy produced by SLM can be used in the computer simulation and development of new manufacturing methods of the metallic parts by additive technologies with the use of deformation post-treatment. © Published under licence by IOP Publishing Ltd.

Abstract

Parametrization of aluminum powders and boron carbide with the use of static analysis of powder images is carried out as a preparatory technological stage for the production of Al/B4C layered metal matrix composites. The results of the analysis of geometric parameters and morphological features, as well as size distribution of aluminum powder particles of different grades and boron carbide of different compositions, have been obtained using a SIAMS 700 image analyzer.
