本文按混合组织的相成分把复相处理归纳为铁素体-马氏体、贝氏体-马氏体和马氏体-残留奥氏体(或贝氏体-残留奥氏体)混合组织三大类;就它们的复相热处理工艺、对组织与机械性能的影响、工业生产的应用及今后基础理论研究等问题,结合作者在这方面的试验研究工作和文献,作了简单的介绍;提供了有关性能数据,分析了有待解决的问题并对复相热处理今后理论与实践的发展,阐述了自己的观点和见解。
Based on the phase composition of the mixed microstructure, the complex phase treatment is summarized as mixed ferrite-martensite, bainite-martensite and martensite-retained austenite (or bainite-retained austenite) Three categories; on their complex heat treatment process, the impact on the organization and mechanical properties, the application of industrial production and future basic theoretical research and other issues, combined with the author’s experimental work in this area and literature, made a brief introduction; Provided relevant performance data, analyzed the problems to be solved and elaborated his own opinions and opinions on the development of theory and practice of complex phase heat treatment in the future.
