摘要：
The influence of aging treatment on the work-hardening behavior of near-equiatomic NiTi alloy has been studied at the microstructural scale by conducting the instrumented indentation measurement. The maximum shape recovery is achieved at the peak aged condition. The improvement in shape recovery has been attributed to the delayed onset of plasticity. A comparison has been made between the recoverable strain obtained from the tensile experiments and the recovery index parameter determined from the nanoindentation measurements.
