Abstract：Directional solidification technique was used to determine the effect of Ce on the solidification structure of low-sulphur 16Mn steel: The results show that addition of Ce increases the primary dendrite arm spacing and decreases the secondary dendrite arm spacing, the width of Columnar region, the size of equiaxed grains and the degree, of micro-segregation of Mn. This technique is expected to be used to reduce the detrimental influence of impurity particles on solidification structures. 收稿日期: 1987-03-18      基金资助:中国科学院科学基金 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 胡汉起 钟雪友 韩青有 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/176 1 钟雪友,胡汉起,刘昌明.北京钢铁学院学报,1984;(3) :16 2 Flenings M C.
