The reverse Monte Carlo method was used to deduce 3-dimensional discrete distributions, of constitutional atoms in melt-spun metallic glasses, from neutron and X-ray diffraction data. It was found that icosahedral short-range order was less stable in the Cu-Zr binary alloy than in the Ti-doped ternary alloy. This investigation also provided evidence of medium-range order; characterized by nanoscale clusters of defects in the metallic-glass state.
