Electrochemical potential equilibrium of electrons in ideal metallic glasses based on the cluster-resonance model
源于“团簇-共振”模型的理想金属玻璃电子化学势均衡

Ideal metallic glasses are the metallic glasses that satisfy electronic structure stability. Previously we have developed a so-called `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 the number of glue atoms. By examples of Cu-Zr and Co-B bulk metallic glasses, it is confirmed that the experimentally determined good BMG-forming compositions well agree with the calculated composition formulas.
