Ce, Y, La, Nd and Sm may increase the solubility of C in liquid iron. The temperature dependences of interaction coefficients between rare earth elements and carbon in either carbon saturated or dilute liquid iron were estimated. It has been proved that various REC_2 are formed in liquid iron under observation of metallography and SEM. The temperature dependences of the equilibrium constants of the reactions of REC_2 formation and the standard free energy of formations of REC_2 in liquid iron were also determined. Five equilibrium diagrams of rare earth elements and carbon have been drawn. 收稿日期: 1987-04-18      基金资助:中国自然科学基金会科学基金资助课题 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 杜挺 乐可襄 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I4/385 1 吴夜明,杜挺.钢铁研究总院学报,1983;3(2) :162 2 王龙妹,杜挺.钢铁研究总院学报,1984;4(4) :481 3 Sigowth G K, Elliott J F.
