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。
