| 摘 要： | 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。

| Abstract: | 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. |
