The Al–B–Nb–Ti system: III. Thermodynamic re-evaluation of the constituent binary system Al–Ti

The thermodynamic description of the binary system Al–Ti is obtained by modelling the Gibbs energy of all individual phases using the CALPHAD approach. The model parameters have been evaluated by means of the computer optimization module PARROT, available within Thermo-Calc, taking into account recent experimental data and critically assessed information on phase equilibria and thermodynamic properties. The calculations are in close agreement with the experimental data on both phase equilibria and thermodynamics in the entire Al–Ti system.
