Abstract：The alloyed amount of Ce in aluminum of commercial purity has been deter-mined by using radioactive isotope ~(14)Ce and by the method of low tempera-ture electrolysis in organic electrolyte.The distribution of alloying Ce in the Alhas also been detected by means of EPMA,autoradiography and autoradiographySEM.Results showed that the most of Ce in Al is in an alloying state and im-pels the enrichment of Si along grain boundaries.The compounds of CeAl_4 andCe_5Si_3 in the Al as well as the eutectic network structure at grain boundary arefound with the increasing of the amount of Ce contained.The Ce is obviouslyenriched itself along the grain and dendrite boundaries in the as-cast Al withor without annealing. 收稿日期: 1985-05-18      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 霍成章 韩其勇 吴尚才 汪良宣 张捷宇 李宝山 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/116 1 Venkatesan,P.S.;Buzash,S.,Metall.Trans.,1(1970) ,2638． 2 中岛勝久;井上定雄,古河电工时报,(1972) ,4月. 3 冶金部广州有色金属研究院,高强度、高导电稀土铝合金导电材料研制报告,1979． 4 Raman,A.,Z.Metallk.,68(1977) ,163． 5 北京有色金属与稀土应用研究所,北京电线二厂,混合稀土-铝合金在软电缆上的应用研究(会议资料),1980,10． 6 梁保国,关于铝镁硅稀土合金导线在跨长江输电路线上的应用,1981． 7 冶金部广州有色金属研究院,稀土铝合金在电线电缆中的应用,1982． 8 #12 9 Han Qiyong;Wu Weijiang;Fang Keming;Huo Chengzhang;Zhou Xiaolong,Proc.of Sino-Japanese Symp.on Iron and Steel,First Symp.on Steelmaking,Beijing,1981,p.25;钢铁,(1982) ,№ 2,1． 10 陈冬;韩其勇;王涛,铁液中La-S-O平衡常数的测定,(待发表). 11 Gschneidner,K.A.,Jr.,Bull.Alloy Phase Diagr.,2(1981) ,224． 12 Games de Mesquita,A.H.;Buschow,K.H.J.,Acta Crystallogr.,22(1967) ,Pt.4,497． 13 钟伟珍;韩其勇;霍成章;刘秀琨;姜玉贤;李晓光;张子荣,球化剂在铸铁各相中含量的测定及其显微分布(待发表). 14 Gschneidner,K.A.,Jr.,Bull.Alloy Phase Diagr.,2(1981) ,158 No related articles found!
