Aiming to obtain a reliable description of the ternary Ag–Al–Cu system the thermodynamic evaluation of the constituent binaries Ag–Al, Ag–Cu and Al–Cu are revised by modelling of the Gibbs energy of all individual phases using the CALPHAD approach. The model parameters have been evaluated using a computer optimisation technique based on the established descriptions of the systems and taking into account the data on thermodynamic properties and phase equilibria both reported in recent publications and obtained by own measurements. The phase diagrams and the thermodynamic properties calculated with the evaluated parameters are in good agreement with the corresponding experimental data.
