摘要
The quasi chemical approximation (QCA) for strongly interacting systems has been applied to study ordering and glass formation tendencies in metal-metal and metal-nonmetal liquid alloy systems; in this case Cu-Zr and Cu-Si at temperatures of about 1499 and 1599 K, respectively. While the QCA results show good agreement with experimental thermodynamic data for Cu-Zr which manifested high tendency to glass formation at Zr concentrations greater than 0.6 atomic fractions, the agreement of the QCA results with experimental thermodynamic data for Cu-Si were not in good agreement suggesting some limitations to the QCA formulations.
