It was resulted that at the cooling rate about 10~5—10~6 K/s, their metastable limit solid solubility is 1.0, 1.5, 2.5, 3.0 and 6.0 at.-% respectively, which is directly proportional to the contractions of the lanthanide and conform to the authors' proposal on a(A)-A_mB_n eutectic systems. The solid solubility in equilibrium has been discussed. 收稿日期: 1983-06-18      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 宁远涛 郑云 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I6/67 1 周新铭;靳嘉禄;宁远涛;赵钟民,金属学报,18 (1982) ,534． 2 宁远涛,金属学报,19 (1983) .A 346． 3 Staudhammer, K.
