By application of the values obtained through the approach to the calculation of the Fe-C phase diagram, the results in the equilibrium region are in very good agreement with the experimental one. From the scattered and limited experimental activity data, the C-C interaction energy obtained through the present approach should be more reasonable than that through previous efforts. Further analysis indicates, however, that up to now the activity data on carbon in ferrite are not accurate enough for obtaining the C-C interaction energy in ferrite with the clear physical significance. 收稿日期: 1987-04-18      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 牟翊文 徐祖耀 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I4/329 1 Kaufman L, Radcliffe S V, Cohen M.
