The fine structure of ferrite and cementite as well as the character of interface combination between the two phases in pearlite have been studied. The fracture process, which is characterized by layer structure was discussed in the term of crystallography. To evaluate the toughness level of pearlitie steels, a new macro-parameter, size of SOCC group, has been suggested. 收稿日期: 1987-03-18      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 黄孝瑛 郭薇 潘天喜 赵坚 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/200 1 Darken L S, Fisher R M.
