Ce对形状记忆合金抗高温失效的影响

Effect of Adding Ce on Stabilization at High Tempreture of Cu－Zn－Al SMA

通过实验研究，分析了Ｃｅ对Ｃｕ－Ｚｎ－Ａｌ形状记忆合金抗高温失效的影响，并对其高温失效的主要原因进行了理论探讨．

Adding small amount of the rare earth element Ce on the Cu－Zn－Al SMA，can prevent the stabilization at high tempreture．Analysis by x－ray and TEM proves that ap-pearing new phase at high temprature is the main reason leading to stabilization，which is α_1bainite．
