The formation of intragranular ferrite on inclusions was later than that of ferrite allotriomorphs at austenite grain boundaries within the temperature range of 650-750℃. The undercooling for the formation of ferrite on inclusions is 40℃ larger than that at austenite grain boundaries. For the former the measured growth rate constant was smaller than that calculated, and for the latter the measured growth rate constant was larger than that calculated. Key words： microalloyed steel    intragranular ferrite    grain boundary ferrite 收稿日期: 2005-08-08      ZTFLH:  TG111，TG142   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 吴开明 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2006/V42/I6/572 [1] Mabuchi H, Uemori R, Fujioka M.
