The results obtained are as follow:(1) The microappearances of fracture surface of flakes are a mixed fracture mode of quasicleavages and intergranular tearing waves.(2) The direction of the crack propagation of flakes are mostly along {112} planes of ferrite. These planes are also quasicleavage facets. While the orientation of the dendritic surface of flakes are {111} planes.(3) There are positive segregations of P, Mn, Mo, Cr and Si on the fracture surface of flakes, among which the most one is phosphorus. 收稿日期: 1981-01-18      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 陈廉 刘民治 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I1/20 [1] Heller, W., Weber, L., Hammerschmid, P. und Schweitzer, R., Stahl Eisen, 92 (1972) , 934． [2] 陈廉、徐永波,尹万全,金属学报,14(1978) ,253． [3] 陈廉、刘民治、张维斗、刘盛炎、尹万全、胡魁毅、孙继红,金属学报,15(1979) ,446, [4] 罗阳,金属学报,13(1977) ,93． [5] 大谷南海男,金属塑性腐食反应,产业图书,1972,p.172;194． [6] Wallace, J.
