摘要：
Thermodynamic assessment of the Cu - Sc system was carried out using the CALPHAD method. A set of self-consistent model parameters was obtained with the usage of the information about phases equilibria and thermodynamic. Gibbs energy for the liquid phase was assessed within the framework of the model of ideal associated solution. Optimized model parameters make it possible to reproduce satisfactorily the phase diagram and thermodynamic values. Analysis of the relative thermodynamic stability of supercooled melts and competing, crystalline phases let its to predict their glass forming ability by rapid quenching from the liquid state.
