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 Al90Y10 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 Al in the binary alloy, and that some of these Al atoms are replaced by Ni atoms in the ternary alloy.Keywords
