The thermodynamic modelling of the binary Al-Zr system has been carried out using the CALPHAD approach, based on available experimental and theoretical data for phase diagram and thermodynamic properties. A set of self-consistent thermodynamic parameters was established. The liquid phase and the terminal fcc_A1(Al), bcc_A2(Zr), hcp_A3(Zr) solid solutions were treated as disordered solutions, using the Redlich-Kister expressions for the excess Gibbs energy, and the intermetallic phases were considered to be line compounds. A satisfactory agreement was achieved between the experimental data and the calculated results.
