摘要：

X-ray << single >> crystal precession photographs of an Al63.5Cu24Fe12.5 alloy of icosahedral symmetry are presented [1]. All the diffraction peak positions are interpreted within the framework of a very simple microcrystalline model in which coherent crystalline domains having particular orientational relationships restore the icosahedral symmetry on diffraction patterns. A quasicrystalline model in which phason fields are introduced is also discussed.
