Analytical determination of partial and integral properties of the six components systems Ni–Cr–Co–Al–Mo–Ti and their subsystems

In the present study, in order for the analytical determination of partial and integral properties associated with the six components alloy systems in the liquid phase, the results of some thermodynamic prediction methods were applied to the Ni–Cr–Co–Al–Mo–Ti system of six components and Pb–In–Sb subsystem with three 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 enthalpy and activity dependences on composition for the investigated cross sections, XCo/XCr=1, XMo/XCr=1, XTi/XCr=1, r=XAl/XCr at 2000 K and In/Sb=1/1 at 973 K, were obtained according to the applied models. The comparison among the results of the three models and experiments shows good mutual agreement.
