Abstract

Atomic structures of amorphous and icosahedral Al75Cu15V10 alloys were precisely examined by the ordinary and anomalous X-ray diffraction techniques. Some distinct features of intensity profiles, and coordination numbers and interatomic distances determined from the RDF analysis, indicate the presence of the icosahedral short-range ordering clusters in the as-quenched amorphous sample and other annealed amorphous samples, which are similar to the basic atomic structure constructing the icosahedral phase. The intensity differences of the amorphous and icosahedral phases obtained in the anomalous X-ray scattering (AXS) at the Cu K-absorption edge suggest that copper atoms are homogeneously dispersed in the icosahedral short-range ordering clusters.
