本文根根国内外的研究成果和笔者本人的一些观察分析,总结了板条马氏体的形态、亚结构、晶体学及其机械性能方面的新近发展情况,其中包括板条马氏体的组织构成、板条马氏体光镜形态的分类、影响光镜组织的因素、板条马氏体的两种立体形态、板条马氏体的惯习面与位向关系、相隣马氏体板条的旋转位向、马氏体—奥氏体界面的台阶结构、板条马氏体的形成过程、板条马氏体的亚结构、板条间的残留奥氏体薄膜、以及板条马氏体的组织结构与机械性能间的关系。笔者在马氏体束、马氏体块、马氏体板条及旋转位向组,板条马氏体两种立体形态,残留奥氏体薄膜的形成机理等十几个问题上还提出了自己的分析意见。
Based on the research results at home and abroad and the author’s own observations, this paper summarizes recent developments in lath martensite morphology, substructure, crystallography and mechanical properties, including the lath martensite organization , The classification of lath martensite light microscope, the factors affecting the microstructure of light microscope, the two kinds of three-dimensional shape of lath martensite, the habitual surface and orientation of lath martensite, the adjacent martensite The rotational orientation of the slab, the step structure of the martensite-austenite interface, the formation of lath martensite, the substructure of lath martensite, the retained austenite film between laths, and the lath The relationship between martensite structure and mechanical properties. The author also proposed in more than a dozen issues such as martensite beam, martensite bulk, martensite lath and rotational orientation group, lath martensite two dimensional forms and the formation mechanism of residual austenite film Own analysis opinion.
