时效对Cu-Al-Ni合金形状记忆能力的影响

Effects of Ageing on Shape Memory Capacity of Cu—Al—Ni Shape Memory Alloys

着重讨论时效对Cu-Al-Ni形状记忆合金记忆能力变化的动力学规律。实验结果表明,时效温度愈高,记忆能力的衰退愈严重。还提出了一个估算形状记忆合金使用寿命的方法。

This paper deals with the dynamic rule of change of shape memory capacity in Cu-Al-Ni SMA during ageing. The results show that the higher the ageing temperature is, the more serious the shape memory capacity fails. Moreover. a method for estimating the service life of SMA is also suggested.
