S, P, along grain boundaries of as-cast structure and of austenite in the high speed steels as well as the cleaning action of RE elements have been studied by AES. It was found that the more S and P the steels contain, the more their segregation occurs. The segregation becomes remarkably improved by the addition of RE elements, and the enrichment of S at grain boundary goes so far as to vanish when the RE added up to 0.05-0.08％. Some discussion on the segregation and the cleaning action have been also made. 收稿日期: 1983-04-18      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 罗迪 邢国华 邹惠良 严申生 俞志中 罗兴华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I4/121 1 Oudar, J., Int.
