摘要: The microstructure, martensite transformation behavior, thermal stability, and shape memory behavior of Ti-20Zr-10Ta high temperature shape memory alloy were investigated. The Ti-20Zr-10Ta alloy exhibited the reversible transformation with the high martensite transformation temperature of 500℃ and good thermal stability. The alloy displayed the elongation of 15% and a maximum recovery stain of 5.5% with 8% pre-strain.
