本文以金相、X射线衍射和透射电镜方法研究了Fe-Mn-Al-Cr系亚稳奥氏体中形变α′-马氏体的形成,证实了它产生于ε-马氏体片相交区,且主要通过γ(?)ε(?)α′和ε(?)α′转变形成。通过回归分析方法建立了形变α′-马氏体量与合金成分的经验关系。
The formation of deiormation α'-martensite for metastable austenite in anFe-Mn-Al-Cr system has been studied by metallography,X-ray diffractionand transmission electron microscope.It has been proved that α′-martensiteformsd mainly by γ(?)ε(?)α′,ε(?)α′tran
