The results show that the relationship between driving force and σ_(0.2)(M_s) can be expressed as: AG~(α→M)=A'σ(M_s)+908 J/mol wher eA' is a constant which slightly deviated for different methods. The M_s temperatures of Fe-Ni-C alloys have been calculated, and the results of calculation are in good agreement with the previous experimental values. 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 李箭 徐祖耀 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I4/321 1 Zener C.
