形状记忆合金（SMA）是一类在塑性变形后经历可逆形状变化的材料。由于加热到临界温度时的结构转变，原始形状的恢复是可能的。形状记忆效应与从低对称性相（马氏体）到高温相（母相）的马氏体-奥氏体转变有关[1]。Cu基形状记忆合金具有大的导热性和导电性的优点，并且Cu-Al-Ni合金系统由于对老化现象具有更好的稳定性而非常有吸引力[2]。
Shape memory alloys (SMAs) are a class of material that undergoes a reversible shape change after a plastic deformation. The recovery of the original shape is possible due to a structural transformation upon heating to a critical temperature. The shape memory effect is related to a martensitic-austenitic transformation from a phase with a low symmetry (martensite) to a high-temperature phase (parent phase) [1]. Cu-based shape memory alloys have the advantage of large thermal and electrical conductivities and the system Cu-Al-Ni alloys are quite attractive due to better stabilisation against aging phenomena [2].
