Anomalous X-ray Scattering on Amorphous Al87Y8Ni5 and A190Y10 Alloys

Abstract

The structure of a new amorphous Al87Y8Ni5, indicating high strength and good ductility, was studied by anomalous X-ray scattering (AXS). For comparison, a binary amorphous A190Y10 alloy was also investigated. The environmental radial distribution functions around Y and Ni as well as the ordinary RDF in the ternary alloy, and the environmental RDF around Y and the ordinary RDF in the binary alloy were determined. From the analysis of these RDFs it is found that the Y atoms are completely surrounded by A1 in the binary alloy, and that some of these A1 atoms are replaced by Ni atoms in the ternary alloy. © 1989, Verlag der Zeitschrift für Naturforschung, All rights reserved.
