It was found that the hot strength of the steel is no longer decreased and the structural stability is dependent on the shape and distribution of NbC after long-time aging at 650℃. The coarse prior NbC deteriorates the structural stability and promotes the decomposition of matrix and the growth of x-phase which embrittles the steel. Thus, it seems to be considered to cut down the Nb content in the steel. 收稿日期: 1984-06-18      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 张弗天 苏丽娟 张彦生 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I6/411 1 张彦生;王明贤;赵学军;许义奎;朴凯东,钢铁17(1982) ,No.4,45． 2 张彦生;张弗天;高会友;王根元,金属学报,20(1984) ,A1． 3 Heikkinen, V.
