一、前言马氏体的惯习面决定了马氏体的形态,而马氏体的形态又决定了马氏体的机械性能。关于马氏体的惯习面、形态和机械性能三者之间的关系,是当代马氏体理论的精华所在。本文以K-S理论为基础,分析了高碳马氏体转变时原子运动和奥氏体与马氏体分别进行塑性变形的情况,从而发现了高碳马氏体的惯习面、显微组织和机械性能之间的一些关系,为进一步通过控制组织,改进性能,提出必要的理论基础。
I. Introduction The habit of martensite determines the morphology of martensite, which in turn determines the mechanical properties of martensite. The relationship between martensite habitus, morphology and mechanical properties is the essence of contemporary martensitic theory. Based on the KS theory, this paper analyzes the atomic motion and the plastic deformation of austenite and martensite respectively during the transformation of high-carbon martensite, and then finds the habit plane, microstructure and microstructure of high carbon martensite Some of the relationship between the mechanical properties, in order to further control the organization, to improve performance, the necessary theoretical basis.
