Abstract

Anomalous X-ray scattering experiments were performed on Zr 63Ni 25Al 12 bulk metallic glass. The results were analyzed using reverse Monte Carlo modeling to obtain localand intermediate-range atomic configurations of this good metallic glass former. Although the Al-related partial information is not reliable due to the small values of their weighting factors in X-ray scattering, good partial information could be obtained from a reverse Monte Carlo analysis. The obtained structural information is given by parameters such as bond angle distributions, bond orientation order parameters, the Warren-Cowley order parameters, and Voronoi polyhedra. Results are compared to the previous results from Fukunaga et al. using X-ray and neutron total scattering.
