The stress-strain curves of Cu-Zn-Al alloys at different temperatures have been plotted on the tensile machine with the aid of electrometry. The main results were as follows: 1. When specimens were deformed within the range of M_s and M_d, the critical stress for inducing martensitic transformation increased with the temperature, and there existed a linear relationship between them. 2. When specimens were deformed above Af, complete pseudoelasticity might be obtained theoretically, which might be damaged, h...

在拉力试验机上用电测法测绘了Cu-Zn-Al合金在马氏体相变点上下各温度的σ-ε曲线，所得主要结果如下：(1)试样在M_s与M_d之间加载，随着温度升高，诱发马氏体相变所需临界应力增大，且加载温度与临界应力之间存在着线性关系；(2)在A_f点以上加载，理论上可获得完全的伪弹性，但加载温度过高或应变量过大，均会损害伪弹性；(3)试样在M_s点上下温度区域变形，得到的伪弹性回复和形状记忆回复之和在80%以上，但在M_s点附近总回复量出现一极小值，且伪弹性回复在M_f点以下又有所回升。
