摘　　要：对不同固溶温度对Cu-18Al-10Mn形状记忆合金的记忆性能和马氏体转变温度的影响进行研究。结果表明,在650℃至900℃范围内,经淬火加沸水时效,合金的形状回复率随着固溶温度的升高而升高,在850℃左右达到最大值,并趋于平缓。随着固溶温度的升高,合金的马氏体转变温度提高。The effect of solid-solution temperature on the shape memory effect and martensite transformation temperature of Cu - 18Al - 10Mn alloy were studied. Experiment results showed that after quenching and up-quenching heat treatment, the shape recovery rate of the alloys increased when the solid-solution temperature changed from 650℃ to 900℃, and reached the maximum value at 850 ℃. With the solid-solution temperature increasing, the temperature of martensite transformation increased.

关 键 词：形状记忆合金 形状回复率 固溶温度
