Abstract

An analytical expression of the excess free energy function for the concentrated ternary solution is described by incorporating the higher order ternary parameters.The appropriate functional form associated with these parameters is derived based on the concept of the interaction parameter formalism.The present equations are capable of interpreting the experimental activities in the Ag-Au-Cu and Fe-Cr-Ni systems at 1350 K and 1873 K respectively. Using the second order parameters, it has been shown that there exists a decreasing trend in the standard deviations in terms of the experimental excess properties of the systems relative to those of the conventional function involving first order parameters.The derived values of various constants are susceptible to Physico-Chemical interpretation based on the central atoms model.
