This RE ladle deoxidizer in amount of 0.08 wt-％ of the melt produces inclusions of Ce_2S_3, CeS, La_2S_3, etc. which tend to increase the fatigue life of the steel by 50％. 收稿日期: 1984-04-18      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 许传才 张隆水 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I4/303 No related articles found!
