本文根据国内外文献和作者的研究结果,讨论了碳和氮对马氏体和奥氏体的点阵参数、马氏体的晶体学、形态学及形态的转化点、马氏体的转变温度、残留奥氏体量、马氏体转变热力学、马氏体组织的强度、硬度等相变因素的影响,找出碳和氮作用的异同点,提出碳氮共存时碳氮原子之间会产生交互作用。 According to the domestic and foreign literatures and the author’s research results, the lattice parameters of martensite and austenite, the crystallographic, morphological and transformation point of martensite, the transition temperature of martensite , Retained austenite, martensitic transformation thermodynamics, martensite strength, hardness and other phase-change factors, to find the similarities and differences between the role of carbon and nitrogen, that carbon and nitrogen atoms will be generated between the carbon and nitrogen atoms Interaction.
