The non-metallic inclusions. in which the graphite coating was already occurred.formed in the dissolution region. They dissolved into the melt soon. but the inclusions coatedby graphite could exist for a longer time. The function of inoculant is to create an undercool-ing solution for carbon. thereby the non-metallic inclusions in the solution may be activatedas a nuclei for graphite. Key words： inoculation    cast iron    activated nuclei    graphite 收稿日期: 1993-05-18      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 王春祺 杨继光 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1993/V29/I5/63 1 Wang Chunqi.
