Prediction of solid + liquid equilibrium diagrams for binary mixtures forming solid solutions with an extremum
Abstract
Convenient methods of correlation and prediction of S+L diagrams exist only for systems forming eutectics. To deal with solid solutions, the model of strictly regular solutions of Guggenheim was adopted. The key assumption is that values of the Gibbs function of interchange w are different in the two coexisting phases: w/sub S/ and w/sub L/. The assumption is based on the fact that the average interatomic distances anti-R are also different, and this affects the averages of the interatomic (or intermolecular) potentials. The input parameters are enthalpies and temperatures of melting of pure components and any pair of experimental points on the diagram. For a number of binary alloy systems the agreement with the experiment is good. Calculations were also made for organic mixtures, again with good results.
