Abstract :
Quasicrystals have additional elastic degrees of freedom not found in conventional crystals, which are termed phason degrees of freedom. Dislocations in quasicrystals are special in that they are inevitably accompanied by the phason strain in addition to the conventional elastic strain. Characteristic features of such quasicrystalline dislocations and plastic properties of quasicrystals are reviewed. Deformation mechanisms in quasicrystals by dislocation motion are discussed.
