其中 Fe-Mn-Si 合金是最新研制出来的一种新型记忆合金，具有高形状记忆性和较好的加工性能
为了更好的理解其记忆行为，本文提出了一个新的方法——约束态的应力诱发马氏体相变
通过实验验证，发现约束态的应力会显著促进马氏体相变，进而提高记忆效应
本文将重点探讨 Fe-Mn-Si 合金的约束态应力诱发马氏体相变的机制，以及其对形状记忆性能的影响

Fe-Mn-Si alloy is a newly developed type of memory alloy with high shape memory and good processing performance
In order to better understand its memory behavior, this paper proposes a new method-Stress-induced martensitic transformation in constrained state
Through experiments, it was found that stress in the constrained state significantly promotes martensitic transformatio
