The results indicate that the activity coefficient of Cu increases and of Fe decreases with the increase of C content. On the basis of data obtained, the first and second order activity interaction coefficients in Fc-Cu-C systcm and interaction coefficients of free energy or enthalpy at constant activity as well as the partial molar heat of mixing of C affected by the Cu content were estimated. Compared with the thermodynamic functions of other Fc-j-C systems after previous works, the regular correlation between these thermodynamic properties and the atomic number of j element seems to be noticeable. 收稿日期: 1983-03-18      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 彭瑞伍 汪光裕 张俊岳 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I3/77 1 Iwase, K., Okamoto, M., Amemiya, T.; Sci.
