An updated thermodynamic modeling of the Ga-Ti system

The thermodynamic description for the Ga-Ti system has been updated using the CALPHAD approach. By combining the existing experimental data and newly obtained results from ab initio calculations and cluster variation method (CVM), the Gibbs energy functions of the individual phases of the Ga-Ti system have been evaluated. Compared with the previous thermodynamic modeling, the present assessment shows a better agreement with the experiments and the calculated enthalpies of formation of the intermetallic compounds obtained from ab initio calculations.
