Local Atomic Arrangement of Amorphous Zr₅₀Ni₅₀ Alloy Analyzed by AXS-RMC Method

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 Zr₅₀Ni₅₀ Shows No Further Features Related to the Crystal-Like Chemical Short Range Ordering (CSRO).
