Results showed that the cleavage element on the fracture surface increases and the impact toughness decreases as the increasing of P content. The intergranular fracture appeared till P up to 0.020%. An impact toughness sequence of various structures in the steel influenced by P may be arranged as: martensite+bainite>bainite>pearlite. 收稿日期: 1986-06-18      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 朱勋 李立丹 王聚才 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I6/86 1 Jokl, M.L.; Kameda, Jun.; McMahon, C.J., Jr.; Vitek, V., Met.
