Abstract

The quaternary TixZr1-xMnFe gettering alloys (x =0, 0.1, 0.2, 0.3 and 0.4) were synthesized successfully by arc melting and their phase structures along with microstructures had been investigated by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). It showed that the addition of Ti did not change the phase structure of ZrMnFe of C14 laves phase. XRD results showed that Ti successfully replaced part of the Zr and the decrease of interplanar spacing had a linear relationship with the increase of Ti content. The success of this trial preparation provides reference for nuclear industry gettering materials.

Abstract

TiB2/7055 composite was synthesized by a new melt direct reaction from 7055-(Al-3B)-Ti system with ultrasound. The phase composition and the microstructures of the as-prepared samples were investigated by XRD, SEM and EDS. The result shows that no Al3Ti phase is in existence. With the assistance of ultrasound, grains are significant refined. Moreover, the wettability between matrix and particles is improved. The shapes of TiB2 particles are mainly hexagonal or near-spherical, and the size is about 500nm. TiB2 particles are with uniform distribution. Compared with 7055Al matrix alloy, the tensile strength of the composite reaches 303MPa, increased by 10.2%. However, the elongation is 7.3%, decreased by 4.8%.
