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.
