Abstract：The Snoek-Kster relaxation processes in oxygen-doped high purity polycrys-talline Ta after plastic deformation were investigated.It was shown that there arefour distinct types of Snoek-Kster relaxation,namely,SK-1 and SK-2 occurringin lower oxygen concentration,i.e.,unsaturated interstitial atmosphere,as sameas peak(1)and(2)in the previous work by the authors;SK-4 in high oxygenconcentration,i.e.,saturated atmosphere and SK-5 in lower oxygen concentration,i.e.,unsaturated atmosphere.The activation parameters of these relaxations weredetermined.As the increasing of the annealing temperature and oxygen content,the gradual transition from SK-5 into SK-4 relaxation can be observed.All relax-ation processes other than SK-1 are stable on annealing.A comparison of resultsbetween previous works and this study was also made. 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 李广义 潘正良 张进修 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I1/25 1 潘正良;张进修;李广义,金属学报,21(1985) . 2 Seeger,A.;Weller,M.;Diehl,J.;Pan,Z.L.(潘正良);Zhang,J.X.(张进修),K,T.S.(葛庭燧),Z.Metallk.,73(1982) ,1． 3 Schoeck,G.;Mondino,M.,J.Phys.Soc.Jpn.,18(1963) ,Suppl.1,149． 4 De Lamotte,E.;Wert,C.A.,J.Phys.Soc.Jpn.,19(1964) ,1560． 5 Van Ooijen,D.J.;Van der Goot,A.S.,Philips Res.Rep.,22(1967) ,150． 6 Delobelle,P.;Oytana,C.;Varchon,D.,Mater.Sci.Eng.,29(1977) ,261． 7 Oytana,C.;Varchon,D.,Acta Metall,27(1979) ,17． 8 Rodrian,U.;Schultz,H.,Z.Metallk.,73(1982) ,21． 9 Schulze,K.,J.Met.,33(1981) ,№ 2,33． 10 张进修;潘正良,金属学报,21(1985) ,待发表.
