      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 αʺ-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.
