Thermal stability and high-temperature shape memory effect of Ti–Ta–Zr alloy

The effect of Zr content on the thermal stability of martensite transformation and the shape memory effect of Ti–Ta alloy was investigated. Zr addition improved the thermal stability and shape memory effects of Ti–Ta alloys. Ti–20Ta–10Zr alloy exhibited good thermal stability with a peak martensite reverse transformation temperature of 763 K and a recovered strain of 4.6% with 8% pre-strain.
