Abstract
A simple, first order description of the formation of ε- and α′-martensite in meta-stable austenitic Fe–Mn alloys containing 12–35 wt% Mn was developed. Given the initial volume fractions of ε- and α′-martensite in the non-deformed material, it is possible to calculate the evolution of phase fractions as a function of applied strain. An accurate estimate of the initial amounts of ε- and α′-martensite based solely on the Mn content of the alloy, could not be obtained due to the important role of microstructure features and processing conditions on the martensitic transformations.

铁锰二元合金相变评估:成分和塑性应变的影响
摘要
对含 12-35 wt% Mn 的亚稳态奥氏体 Fe-Mn 合金中 ε- 和 α'-马氏体的形成进行了简单的一级描述。给定未变形材料中 ε- 和 α'-马氏体的初始体积分数,可以计算作为外加应变函数的相分数的演变。由于显微组织特征和加工条件对马氏体转变的重要作用,无法仅根据合金的 Mn 含量准确估计 ε- 和 α'-马氏体的初始量。
