Abstract
It has been pointed out that a bulk metallic glass composition could be formulated as [cluster](glue atoms)x, where the cluster is derived from a devitrification phase. However, the selection rule of the so-called principal cluster should be specified because an alloy phase usually contains multiple clusters. In this paper, two important properties of the principal clusters are emphasized, i.e., spherical periodicity and cluster isolation, both being structural features of metallic glasses. According to these two criteria, the principal clusters are rigorously identified in devitrification phases and are used to construct cluster formulas to explain binary bulk-metallic glasses of Cu-(Zr,Hf), Ni-(Nb,Ta), Al-Ca, and Pd-Si.
