Abstract：The“interface withdrawal”across the α/β interface in Cu:Cu-Al diffusioncouples during quenching has been investigated.Using numerical analysis basedon the Fick's second law,the non-isothermal diffusion modeling across the α/βinterface was carried out in comparison with the experimental results.The distan-ce of interface withdrawal depends on the initial concentration profile at thehigh temperature,the diffusion annealing temperature,the diffusion coefficients,the cooling rate and the slope of the solves curves in the phase diagram.Thewithdrawal effect influences the shape of the concentration profile and the inter-facial concentration. 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 吕忆城 M.R.Notis J.I.Goldstein 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/67 1 吕忆城;Notis,M.R.;Goldstein,J.I.,金属学报,21(1985) . 2 Willey,L.A.,Bull.Alloy Phase Diagr.,1(1980) ,№1, 27． 3 Tanzilli,R.A.;Heckel,R.W.,Trans.Metall.Soc.AIME,242(1968) ,2313． 4 Oikawa,H.;Obara,T.;Karashima,S.,Metall.Trans.,1(1970) ,2969． 5 #12 No related articles found!
