An enrichment of Ce was obviously observed by autoradiography to be segregated along the grain and dendrite boundaries in Fe-Cr-Al alloy or Cr24Ni7Si2N when the Ce content is notl ow The microscopic inhomogeneity of Ce distribution is presented among different grains of the Fe-Cr-Al alloy. 收稿日期: 1986-04-18      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 韩其勇 霍成章 钟伟珍 彭鸣 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/15 1 Han Qiyong; Wu Weijiang; Fang Keming; Huo Chengzhang; Zhou Xiaolong, Proc. of Sino-Jpn Symp. on Iron and Steel, First Symp. on Steelmaking, Beijing, 1981, p, 25;钢铁, 16 (1982) , № 2, 1． 2 韩其勇,吴卫江,方克明,张保军,谢德义;裴丽侠,金属学报,15(1979) ,1． 3 zhong Weishen(钟伟珍),Han Qiyong(韩其勇),Huo Chengzhang(霍成章); New Frontiers in Rare Earth Science and Application Vol.Ⅱ, Proc. of the Int.
