Abstract
An anomalous small angle X-ray scattering (anomalous SAXS) method has been applied to obtain a possible origin of structural inhomogeneity in amorphous Zr33Y27Al15Ni25 alloy annealed at 773 K for 300 s. The remarkable decrease in intensity is detected for Ni and Zr whereas an increase is clearly observed for Y, when the incident energy approaches to the respective K-absorption edge. Several models have been tested for describing these new experimental data and the Y-rich phase is suggested to be one of the possible origins for structural inhomogeneity by explaining the anomalous SAXS intensity variations at three absorption edges of Ni, Y and Zr.
