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.
