The rock-salt fracture occurred at the original austeniticgrain boundaries of the steel showed dimples, and the morphology and size ofMnS inclusions located in such dimples varied with different facets even for asingle austenite grain. The Widmannstatten precipitates of sulphide also occurredat the rock-salt fracture surfaces at times. The probable cause and the controllingfactors in regard to the formation of sulphide inclusions in various morphologieshave been discussed. 收稿日期: 1979-04-18      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 赵坚 汪德根 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I4/439 [1] Preece, A., Hartley, A., Mayer, S.
