Abstract
A thermodynamic assessment of the Ti-Ni binary system has been made by applying the CALPHAD method. A set of self-consistent Gibbs energy parameters describing all the present phases in the system has been obtained through a least-squares optimization procedure using the available thermodynamic and phase equilibria information. The calculated phase diagram as well as the thermodynamic functions are in good agreements with the experimental data available in the literatures. The thermodynamic aspects on the glass forming ability in the Ti-Ni system are briefly discussed based on the To criterion. The calculated thermodynamic functions and phase diagrams are presented with the optimized thermodynamic parameters.
