ABSTRACT
Taking the chemical ordering in the metallic glasses into consideration, we have extended the efficient cluster packing model to predict the composition in high-solute concentration alloys with atomic dense packing. Its validity is supported by the good agreements between the predicted compositions with the maximum packing efficiency and the experimentally optimized bulk metallic glass formers in the Cu–Zr, Cu–Hf, and Ni–Nb binary systems. Despite its simplicity, it seems that the structure predicted by our model reflects in certain way the averaged structural configuration of metallic glasses.
