Since the successive layers have facing surfaces with mated topography, it is considered that the seperating of the layer from the reaction front should relate to the diffusion-induced stresses developing within the separating of the layer during solid state reactions. We discovered that the layer is fractal with clusters of phase β(FeSi in diffusion couple Zn/Fe3Si or CoSi in diffusion couple Zn/Co2Si, e.g.) distributing continuously in phase α (FeZn13 or CoZn13, respectively). This empirical fact supports the mechanical-instability model for the pattern formation of periodic-layered structures. Key words： solid state reaction    diffusion-induced stress    periodic-layered structure 收稿日期: 2004-04-29      ZTFLH:  TG111.6   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 陈永翀 其鲁 张永刚 陈昌麒 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2005/V41/I3/235 [1] Osinski K, Vriend A W, Bastin G F, van Loo F J J.
