The assessment of the Co-Zr system was carried out in the frameworks of the CALPHAD-method. Composition dependence of the excess Gibbs energy of liquid alloys and solid solutions in the system was described using Redlich–Kister polynomials. Compound Energy Formalism was used to describe the thermodynamic properties of intermetallic compounds. The current assessment takes into account a complete set of experimental data on the thermodynamic properties of the phases and phase equilibria. The phase diagram, coordinates of invariant equilibria, and thermodynamic properties of liquid and solid phases are calculated.
