Pressure-induced amorphous to amorphous transitions in covalently bonded substances with open local structures have been extensively studied over the years. However, this is not the case for amorphous metallic glasses with closely packed local structures and high coordination numbers. Pressure induced local structural changes in these densely packed disordered systems and its correlation with the anomalous pressure behavior are still poorly understood. We aim to take a further step into this issue by investigating the pressure behavior of closely packed local structures in a simple system, binary Ni62Nb38 metallic glass. We propose to perform structure factor (S(q)) measurements for advanced local structural analysis using the reverse monte carlo refinements applied simultaneously on both S(q) and XAS data (already measured). Using such advanced analysis, goal is to get structural insights beyond the pair distribution level to understand the pressure behavior of closely packed systems
