Abstract

The superelasticity behaviors of Ti-19Zr-11Nb-4Ta shape memory alloy subjected to aging treatments were investigated in this study. As the aging temperature increased, the precipitation of isothermal ω phase was found to suppress the formations of stress-induced α-martensite. The superelastic recovery of the sample first increased and then deteriorated with the increasing of aging temperature from 423 K to 523 K. A maximum superelastic recovery strain of 3.9% was obtained for Ti-19Zr-11Nb-4Ta alloy aged at 473 K.
