钢与铁基合金中马氏体组织形态、晶体结构、相变机理与强韧化理论的研究。不断为创制新钢种、提高材料强韧性和改进热处理工艺规程提供了重要的实验和理论依据。因此,五十多年以来,各国冶金和材料科学工作者以极大的兴趣和注意,为探求马氏体相变的热力学、晶体学、动力学、组织形态与亚结构、强韧化机理等,进行了大量的实验研究和理论分析。随着光学金相、X射线衍射特别是本世纪五十年代以来金属薄膜电子透射技术的迅速发展,使人们对马氏体这一名称逐步得到了较清晰的概念,对金属与合金的成分、马氏体形态与亚结构及力学性能三
Study on Martensite Structure, Crystal Structure, Phase Transformation Mechanism and Toughening Theory in Steel and Iron - base Alloy. Continuously for the creation of new steel, improve material toughness and improve the heat treatment process provides an important experimental and theoretical basis. Therefore, for more than 50 years, the metallurgy and materials scientists of various countries have taken great interest and attention to explore the thermodynamics, crystallography, kinetics, morphology and substructure of martensitic transformation, strengthening and toughening mechanism, etc. , Conducted a lot of experimental research and theoretical analysis. With the rapid development of optical metallography and X-ray diffraction, especially since the 1950s, the thin film electron transmission technology has led to a gradual and clear definition of the martensite. The composition of the metal and the alloy, Martensite morphology and substructure and mechanical properties of three
