Abstract：The diffusion coefficient of carbon in liquid iron has been determined byrotating disk method in the temperature range of 1550--1680℃ under argonatmosphere, the temperature dependence of diffusion coefficient being D=4.76 exp(-38000/RT). It was shown that in the case of either complete deoxidation orwithout any deoxidation, the reaction between solid carbon and liquid iron usu-ally lies in the region of diffusion kinetics. In the former case, the diffusion ofcarbon is the rate controlling factor of the reaction. While in the latter case, theoverall reaction consists of two parallel processes-the solution of carbon andthe reaction of solid carbon with the oxygen in liquid iron. The reaction rate isthen controlled by the diffusion of both carbon and oxygen. 收稿日期: 1980-04-18      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 韩其勇 韩同甫 王俭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I4/435 [1] #12 [2] #12 [3] #12 [4] #12 [5] #12 [6] #12 [7] #12 [8] #12 [9] #12 [10] Elliott, J.
