: The effects of heat treatment on the microstructure and phase constitution of Ti-3Zr-2Sn-3Mo-15Nb (TLM) alloy were investigated by optical microscopy, X-ray diffractometry and transmission electron....
Key words: Ti-3Zr-2Sn-3Mo-15Nb alloy; microstructure; wear resistance; phase constitution; β titanium alloy
of these alloys were studied by X-ray diffraction and electrochemical measurement. The results show that when x are 0, 0.1 and 0.2, the alloys are composed of V-based solid solution as main phase and TiNi phase. When x=0.3, the alloys are composed of V-based solid solution as main phase and laves phase of C14 with hexagonal structure. The unit cell constant and the quantity of unit cell both......V3TiNi0.56Al0.2Crx(x=0 ~ 0.3)贮氢合金的微结构及电化学性能
