Abstract

Mesoscopic structure of two decagonal quasicrystalline samples, Al-Co-Ni and Al-Co-Cu, is investigated by XRD and SEM. Simultaneous SAXS and WAXS (SWAXS) measurements give information on the shape, size, and pair-distance distributions of nanometer-size aggregates contained in the analyzed volume. Decagonal single quasicrystal structures, quasicrystalline approximants, and nanometer-size domain structures are found to coexist in the samples. (C) 2013 Elsevier B.V. All rights reserved.
