Four kinds of surrounding for Fe-atom nucleus are found in the steel The Fe-Ni atom cluster which consists of one Fe atom and two nearest neighbouring Ni atoms (2nnNi) is considered as the critical state of transformation to austenite The atom cluster of this type in the specimen quenched from α+γ region is more than that undergone conventional heat treatment The stable γ′ has yielded more abundant in the former than in the later Futhermore, the γ′-phase increases with the increase of tempering temperature because of the migration and enrichment of Ni atoms. 收稿日期: 1986-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张弗天 姜健 宋建先 韩慈 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/113 1 张弗天;许义奎,能源材料通讯,2(1984) ,58． 2 张弗天;王景韫;郭蕴宜,金属学报,20(1984) ,A405． 3 Lauermannova, J.; Zemcik, T., Phys.
