铜基形状记忆合金的时效敏感性虽早有报道,但马氏体稳定化现象的发现并受到普遍的关注则是近几年的事。人们提出过再有序化、空位钉扎两种解释马氏体稳定化的主要机制。但对马氏体时效稳定化的研究仍然存在很多的疑问和分歧,对原始组织及其缺陷的影响 Although the sensitivity of copper-based shape memory alloys has long been reported, the discovery of martensitic stabilization and its widespread concern have been the subject of recent years. People have proposed reorganization, space pinning explain two of the main mechanisms of martensite stabilization. However, there are still many questions and disagreements about the research on the stabilization of martensite aging, the impact on the original organization and its defects
