Quasi-chemical studies of ordering in the Cu–Zr and Cu–Si melts
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...

| description | 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. |
