摘　　要：通过冷轧和拉伸试验及金相分析,研究了Cu-Al-Mn形状记忆合金的冷加工性能.结果表明,经800℃保温15 min并作固溶处理,再在550℃下保温60 min,此时在β母相上析出较大的α相颗粒,合金的冷加工性能最好,其冷轧变形率为43%,拉伸应变率为6.3%.The cold-working property of Cu-Al-Mn alloy was investigated using cold-rolling test, metallogragh observation,tensile test etc. The results showed that the massive α phases precipitated in the β phases,the deformation rate of alloy was up to 43% ;and the elongation rate was up to 6.3% after solution treatment at 800℃ for 15 min,followed by holding at 550℃ for 60 min.
