Abstract

The atomic structures around Zr and the noble metals M (M = Pd, Pt and Au) were studied by the anomalous X-ray scattering method in amorphous and quasicrystal Zr-based alloys. The prepeak in an energy differential intensity profile at the absorption edge of the M atoms in the amorphous state indicates the presence of a strong chemical short-range order around the M atoms. Coordination numbers and atomic distances were determined in all the samples. The atomic distances of the Zr-M pairs, which are shorter than those calculated from their Gold Schmidt radii, also suggest the existence of strong chemical bonds between them.
