Abstract: The effect of heat treatment on shape memory properties of the ductile CuAlMn alloys was studied. The results show that the heating temperature for the solution treatment should be around 100℃above the transformation temperature in order to obtain good shape memory properties, heating for 10min at this temperature doesn’t have much influence on the shape memory properties, faster cooling rate helps to obtain good shape memory properties and the shape recovery rate(SRR) decreases with raising ageing temperatures. For Cu-16Al-10Mn alloy, the heat treatment process to acquire higher recovery rate is heating at 800℃for 15 min, quenching into ice water and ageing below 150℃for 15 min. For Cu-17Al-10Mn alloy, the process is the same except heating at 700℃.
