Abstract

Structure of Zr₅₀Ni₅₀ amorphous alloy was analyzed by anomalous X-ray scattering (AXS) coupled with reverse Monte-Carlo (RMC) simulation. Topological features in the nearest neighbor atomic configuration clearly suggest that the strong chemical interaction between Ni and Zr breaks the icosahedral-like local ordering structure common in the dense random packing of hard sphere (DRPHS) model. Nevertheless, the structure of Zr ₅₀Ni₅₀ shows no further features related to the crystal-like chemical short range ordering (CSRO).
