An Analytical Approach for Thermodynamic Properties of the Six Components Systems Ni–Cr–Co–Al–Mo–Ti and Its Subsystems

In the present study, the results of some thermodynamic prediction methods were applied to the Ni–Cr–Co–Al–Mo–Ti system of six components. The Chou’s general solution model and the traditional models of Kohler and Muggianu were included in the calculation for the comparison and discussion. The excess Gibbs energy dependences on composition for two investigated cross sections at 2000 K, were obtained according to the applied models. The comparison between the results of the three models shows good mutual agreement.
