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. (C) 2013 Acta Materialia Inc.
