It is found that the actual distribution coefficient of solute is a function of liquid state. An increase of superheat of the melt causes the increase of actual distribution coefficient for such elements of K_0<1, and the decrease of the critical conditions of G/R associated with the stability of the solid-liquid interface morphologies which seems to be available to improving the directional solidification. 收稿日期: 1983-03-18      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 毛协民 傅恒志 史正兴 刘慧铭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I3/84 1 Tiller, W.
