The results show that the amount of carbides diminishes and the relative amount of ferrite increases after normalizing at 950℃. Most of V precipitates in the form of VC and a little dissolves in the cementite. Addition of rare earth suppresses the precipitation of VC markedly. The dissolved rare earth causes CCT curves shift to the right and increases stability of the undercooling austenite, thus changes the form of decomposition products. 收稿日期: 1987-06-18      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 刘宗昌 杨植玑 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I6/531 1 Picketing F B.
