It Was found that a complex ordered carbonitride is formed on hot-rolling and continuous cooling by the precipitation of Nb and V together with C and N in which the contents of Nb and V are changeable. Its concentration ratio, C_(Nb)/C_v, decreases with the decrease of the grain size precipitated. The stoichiometric formula of the precipitate may be (Nb, V) (C_(1-x), N_(1-y)). Electronic microscopic observation revealed that both the morphology characteristics and the crystallographic orientation of the precipitate seem to be identical with ones either in the Nb- or V-steel. 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 徐温崇 孙福玉 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I6/29 1 Baker, R.
