Abstract：The changes during reheating of the supersaturated solution boron in the40MnB steel previously formed by rapid cooling from elevated temperature weredetected by phase analysis and observed by track microphotography(boron autora-diography)and metallography.It was found that the boron-containing phases areprecipitated during heating from supersaturated solution boron as another differ-ent way of precipitation in comparison with that on cooling.X-ray diffractionshows that the major boron-containing phase is Fe_3(C,B),The correlationbetween its amount,size,precipitating rate,sites and heating temperature wasstudied.The similarities and differences as well as the connection each otherbetween these two precipitation ways were also discussed. 收稿日期: 1985-03-18      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 祖荣祥 李定秀 郭曼玖 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I3/22 1 渡边征一;大谷泰夫,铁と钢,66(1980) ,506． 2 #12 3 邦武立郎;渡边征一;杉泽精一,铁と钢,59(1973) ,S565 4 Melloy,G.F.;Slimmon,P.R.;Podgursky,P.P.,Metall.Trans.,4(1973) ,2279． 5 Cameron,T.B.;Morral,J.E.,Boron in Steel,New York,1980,p.61-79． 6 Busby,P.E.;Warga,M.E.;Wells,C.,Trans.AIME,197(1953) ,1463． No related articles found!
