摘要
综合研究了母相的有序度ξ、晶粒尺寸d和在马氏体状态的变形度ε对CuZnAl合金中形状记忆效应的影响。从热力学出发,导出了形状回复率η与上述三种参数之间的统一的数学表达式。理论分析与实验测试结果吻合较好。
The influence-of the degree of order and grain size of the parent
phase as well as the amount of deformation in the martensitic state on the
shape memory effect of Cu-Zn-Al alloys is investigated. A mathematical
expression describing the relationsnip between shape recovery rate η and th-
ese three factors is presented. The theoritical predictions are consistent with
experimental results.
