摘要

The effect of thermo-mechanical treatment on microstructure evolution,martensite transformation,and shape memory behavior of Ti-15Ta-15Zr high temperature shape memory alloy were investigated.Different martensite morphologies were found with different annealing temperatures.The Ti-15Ta-15Zr alloy exhibits almost perfect shape memory recovery strain of 6％ after annealing at 973 K for 0.5 h.
