Abstract：Based on the Miedema′s theory of electric charge shift,a modification of Mo-reen′s model of prediction of the lattice parameters in solid solution was approachedfrom the idea of the atomic size and separation in solid solution changing withsolute concentration.The lattice parameters in both solid solution at equilibrium andextended solid solution prepared by melt quenching seem to be predicted with moreaccuracy.By this modified model,the lattice parameters of Cu-Al,Cu-Si and Ni-Al systems solid solution at equilibrium and Ag-Sn,Ag-La and Ag-Gd extendedsolid solution were calculated.They are in better agreement with the experimentalvalues than the Moreen′s. 收稿日期: 1985-01-18      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 宁远涛 徐桦 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I1/139 1 Moreen,H.A.,Taggart,R.;Polonis,D.D.,Metall.Trans.,2(1971) ,265． 2 Jones,H.,Scr.Metall.,17(1983) ,97． 3 Miedema,A.R.,J.Less-Common Met.,32(1973) ,117． 4 Miedema,A.R.,ibid.,46(1976) 71． 5 Pearson,W.B.;A Handbook of Lattice Spacings and Structures of Metals and Alloys,Pergamon Press,New York,1958,p.304,331． 379,610． 6 宁远涛;郑云,金属学报,19(1983) ,B225． 7 周新铭;靳嘉禄;宁远涛;赵钟民,金属学报,18(1982) ,534． No related articles found!
