This coarse grain fracture, showing one of the priorly overheated coarse austenite grain, is, in reality, fine grain fracture along fine equiaxial austenite grain boundary formed on reheating at medium rate. So it is called the pseudo-inheritance of fracture. It seems to be not affected on the impact toughness. The origin of pseudo-inheritance of fracture has been discussed. 收稿日期: 1987-02-18      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 戚正风 任瑞铭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/158 1 戚正风,刘世程.大连铁道学院学报,1983;(1-2) :21 2 Ko T, Hanson D.
