THERMODYNAMIC OPTIMIZATION OF THE CU-TI SYSTEM

Thermodynamic properties of the Cu-Ti system were optimised using expe rimental thermochemical and phase diagram data from the literature, le ading to a consistent set of Gibbs energy parameters for the thermodyn amic description of its equilibrium phases. Non-stoichiometries of the compounds Cu4Ti and CuTi were taken into account by using appropriate sublattice models. The calculated phase diagram and the thermochemica l properties are compared with the corresponding experimental data.
