摘　　要：研究了Ｚｒ对ＣｕＺｎＡｌ记忆合金性能稳定性的影响。结果表明：Ｚｒ可降低马氏体稳定化倾向，并使合金的中温稳定性增强。Ｘ射线衍射证实，中温时效时，Ｚｒ的加入抑制合金中马氏体有序度的下降与平衡相的析出，这可能与晶粒细化导致过饱和空位浓度的改变有关。ffect of Zr addition on the property stability of CuZnAl alloy was investigated. It showed. Zr- doped could reduce martensite stabilization trend and improve property stability in the mid-temperature. X-ray diffraction results showed that Zr restrained the variation of order parameter and the formation of equilibrium phase when the alloy aged in the mid-temperature.This might have relation with the change of excess vacancy concentration which resulted from grain refining.
