On the basis of the related theoriesof chemical bond an attempt was made to suggest a parametric diagram of chemi-cal bond concerning interaction between graphitic carbon and other atoms in mol-ten cast iron. Three distinguishable regions as spheroidizing, transitional and anti-spheroidizing may be designated. The element distribution in either spheroidizingor anti-spheroidizing region appears to agree fairly well with both experimentsand production practice. Furthermore, a function ρ_i has been taken as the measureof probability of spheroidization for certain elements in the spheroidizing region. 收稿日期: 1979-04-18      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 韦永德 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I4/559 [1] 陈念贻,键参数函数及其应用,科学出版社,1976,p.1． [2] 戴安邦等,无机化学教程,人民教育出版社,1972,p.513． No related articles found!
