摘要：

An icosahedral quasicrystalline phase was found to be formed in rapidly solidified Al-Pd-Mn alloys. The quasicrystalline structure was confirmed to have asuperlattice structure of the simple icosahedral quasicrystal, similar to the face-centred icosahedral structure for Al-Cu-Fe quasicrystals. The intensity of thesuperlattice reflections increases successively with increasing Pd content, and hencePd atoms seem to occupy predominantly the superlattice site rather than thefundamental lattice in the icosahedral structure. © 1990 Taylor & Francis Group, LLC.
