Interface of quasicrystal and crystal

A model on the coexisting phase of quasicrystal-crystal is proposed, with which we concretely investigate the interface effects for coexisting phases of one-dimensional orthorhombic quasicrystal-isotropic crystal and three-dimensional icosahedral quasicrystal-cubic crystal. The phason strain fields which play an important role in some processes are determined. Some factors affecting the strain fields, e.g., the material constants of phonon, phason, phonon—phason coupling of the quasicrystal and the elastic modulus and the size of the crystal are also explored.
