摘　　要：对Ｆｅ－３０Ｍｎ－６Ｓｉ－５Ｃｒ合金热处理过程中ε－氏体量及形状恢复量随温度变化的研究结果表明：应力诱发ε－马氏体较热诱发马氏体对应更高的转变温度。４５０℃回火热马氏体全部逆转变，应力诱发马氏体则部分残留在基体中，这是该系列合金形状恢复量低的原因之一。The study on the variation of reovery strain and volume fraction of εmartensite as a function of temerature for Fe_30Mn_6Si_5Cr SMA prestrained by 3% shows that stressinduced εmartensite transforms at a higher temperature than thermal εmartensite,all thermal εmartensite transforms after being heated to 450℃,but some stressinduced εmartensite can not transform,and this is part of the reason for low recovery strain of Febased SMA
