本文从热力学观点出发,分析了 CuZnAl 形状记忆合金在马氏体状态变形时预变形量对记忆效应的影响,导出了形状回复起始温度 T(?)及形状回复率η与变形量ε的一般关系式为T(ε)=(Aε~2-B_ε+A_s)/(1+Dε)η=M(K_(1ε)-K_2)理论计算与实验结果相符。
From the viewpoint of thermodynamics, this paper analyzes the effect of pre-deformation of CuZnAl shape memory alloy on the memory effect when the martensite is deformed, and deduces the initial temperature T (?) And the shape recovery η and the deformation ε The relationship is T (ε) = (Aε ~ 2-B_ε + A_s) / (1 + Dε) η = M (K_ (1ε) -K_2) The theoretical calculation is consistent with the experimental results.
