摘要：

Al-Cu-Co single quasicrystals were studied by the reflective X-ray topography. It was found that on the surfaces of the single quasicrystals, which were parallel to (00001) decagonal plane, the contrast associated with screw dislocation occurs. In the topograms taken from other surfaces of the single quasicrystals the bands of contrast appear. This contrast comes from the antiphase domains and depends on the conditions of the single quasicrystals growth process.
