The paper studied the influence of Zr content and solution temperature on properties of Cu-Zn-Al SME al oy via metal ographic observation, shape recovery rate test and tensile testing, it concluded that the increase in Zr content within a certain range can improve properties of copper-based SME al oy on shape memory effect, tensile strength and elongation by grain refinement, as wel as raise the performance of al oy cold work; Solution temperature has a significant influence on microstructure and properties of the al oy: typical lath martensite emerged in metal ographic observation at 810℃, shape recovery rate was over 90%with higher tensile strength and elongation.%通过金相观察、形状回复率测试和拉伸试验，研究Zr含量及固溶温度对Cu-Zn-Al形状记忆合金性能的影响。结果表明：在一定范围内，增加Zr含量，可以细化晶粒，提高铜基记忆合金的记忆性能、抗拉强度和延伸率，改善合金冷加工性能；固溶温度对铜基形状记忆合金影响很大，在810℃时，金相呈现典型的板条状马氏体，形状回复率能达到90％以上，抗拉强度和延伸率也较高。
