摘 要:通过高温金相观察,电阻-温度曲线和相变塑性曲线的测定,证实:Cu-Zn-Al记忆合金由于淬火条件的不同,会出现两种不同的马氏体,热弹性马氏体和非热弹性马氏体。停放过程热弹性马氏体的稳定化,与B2→DO3转变受抑制,热弹性马氏体与母相的共格关系受破坏有关。
Abstract: Having observed the high temperature metallograph,measured the resistance -emperature curve and tested the transformation-induced plasticity, it is confirmed that in Cu-Zn-Al memory alloys there appear two kinds of martensite, i. e. thermoelastic and nonthermoelastic, as a result of different conditions of quenching. The stabilization of thermoelastic martensite in the process of store is proved to result from the transformation of the martensite from thermoelastic into nonthermoelastic.
