Furthermore, we believe that the general rules for understanding the superstructures formed within boundary areas are correlated directly with different overlapping or connecting operation with respect to building units of flattened hexagons and P-B polygons. These rules are as following:I The adjoined domains at least have their basic structural units a side-shared (that is, sharing two column clustersП) The basic structural units in both domains have overlapping area as large as possible.3 For theξ-Al-Ni-Rh phase formed in the as-cast Al75Ni15Rh10 alloy, phase transition processes induced by electron beam irradiation with different amount of dose were studied by in-situ observations in an electron microscope.

本论文提出了畴界的通用模型：各种畴界及其畴界处超结构都可以用一个通用的叠加覆盖模型去表示，覆盖的基本单元为扁六边形或P-B多边形，连接与覆盖规则如下：I相邻畴中的基本单元至少有一个共用边相邻畴中的基本单元重叠时沿b方向有最大重叠面积。3研究了Al75Ni15Rh10合金中ξ-Al-Ni-Rh相在透射电镜电镜中经不同剂量电子束辐照后引起的辐照损伤和相变过程。
