Abstract
A model is developed for describing phason defects in quasicrystals in the form of dilation filaments. This model is used to calculate the e nergy of edge dislocations in quasicrystals including the interaction of this type of dislocation with its ''intrinsic'' phason defects and with the equilibrium phason defects present in a quasicrystal. It is s hown that the contribution of ''intrinsic'' phason defects to the tota l energy of an edge dislocation in a quasicrystal is substantial. (C) 1997 American Institute of Physics.
