Ideal metallic glasses are the metallic glasses that satisfy electronic structure stability.Previously we have developed a socalled 'cluster-plus-glue-atom model' and more recently a 'cluster-resonance model' for the ideal metallic glasses.Good metallic glass forming compositions always satisfy simple cluster formulas[cluster](glue atoms),with x denoting the number of glue atoms matching one cluster.In this paper we present an electrochemical potential equilibrium criterion based on these models to obtain t...
