本文对下列几个课题的新、旧观点加以比较,并指出了待解决的一些问题:1.间隙原子在马氏体晶格中的位置;2.取向关系;3.马氏体中的亚结构;4.马氏体的成核;5.与马氏体相关联的其他转变。当作者年青的时候,马氏体是金属学中的时髦课题。几十年过去了,近来对这一课题又进行了广泛的研究。此时,重新考虑旧的观点并评价一些新提出的关于马氏体本性的论点,是有意义的。 This article compares the new and old viewpoints of the following topics and points out some of the problems to be solved: 1. The location of the interstitial atoms in the martensite lattice; 2. The orientation relationship; Structure; 4. nucleation of martensite; 5. other transformations associated with martensite. When the author is young, martensite is a fashionable subject in metallography. Decades have passed and recent research on this subject has been conducted extensively. At this point, it makes sense to reconsider the old point of view and to evaluate some of the newly proposed arguments about the nature of the martian.
