A tiling approach to the recovery of a slip plane and the interfaces between domains in ico-related quasicrystals

A physical displacement across a slip plane or a domain boundary may be resolved into a sequence of phason flips which restore the nearest neighbour configurations and the tile forms of the original quasicrystal. The number or density of required new vertices is correlated with the square of the implied internal space component of the physical shift. Examples are shown which are relevant to domain boundary widths and the ease of progress of physical slip in the relevant quasicrystal.
