Abstract
Several repeat units and repeat schemes for the Al-Cu-Co decagonal phase and its crystalline approximants are proposed. An inherent strain is introduced into the structure through repetition of these units. The transition from the crystalline to the quasicrystalline state appears to be due to an increase in twinning, which reduces this strain.Keywords
