The calculated results agree well with the experimental results for Al-Mn alloy. Key words： sub-rapid solidification    transition from dendrite to fine cell    stability of cylindrical interface 收稿日期: 1997-07-18      基金资助:国家自然科学基金 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 耿兴国 傅恒志 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1997/V33/I7/673 1 Mullins W W,Sekerka R F.J Appl Phys,1964;35:444 2 Boettinger W J, Shechtman D,Schaefer R J,Biancaniello F S.Metall Trans,1984;15A:553 Trivedi R,Kurz W.
