Abstract

The free-volume and interconnecting-zone (i-zone) can be quantitatively determined by distances between the nearest atoms based on the investigation on the pair distribution function data, which were obtained at a cryogenic temperature of 15 K using a neutron scattering source on the Zr₅₅Cu₃₅Al₁₀ bulk metallic glass and its crystallized counterpart. Accordingly, the atomic cluster regions can be determined, i.e. the atoms are regarded in the cluster regions if it is not in i-zones and free volumes. This approach not only helps us for qualitatively analyzing local atomic packing, but also enables us to quantitatively characterize local atomic structures in amorphous alloys.
