形变对铜基形状记忆合金马氏体组织的影响

Effects of Deformation on Martensitic Microstructure in Cu-Based Shape Memory Alloys

采用光学显微镜方法研究了CuZnAl形状记忆合金住马氏体状态下经受不同形变量(ε=5％～45％)的塑性变形之后对金相组织的影响,报导了马氏体再取向、马氏体片内的滑移变形以及一种新的无序面心立方相形成的特征。

Effects of deformation from 5% to 45% on microstructure of CuZnAl shape memory alloys in martensitic state have been investigated by means of light microscope. The characters of reorientation of martensite, slip in martensite and formation of a new disordered F. C. C. phase have been reported.
