摘要

The superelastic behaviors of different isothermal treated Cu-13.8Al-4.0Ni (mass fraction) single crystals were studied by applying tensile stress along ＜001＞ of the β phase. The different isothermal specimens have different superelastic behavior due to the change of the ratio of stress-induced γ＇1 andβ＇1. The superelasticity of γ＇1 phase tends to that ofβ＇1 phase with cycling.Typical stabilization of stress-induced martensite above Ap*P results in residual deformation. Due to the reverse transformation of γ＇1, there is a deviation of pseudo-yield stress from linear relation with temperature at relatively low stress.
