Abstract:

The thermodynamics of interstitial solid solutions and non-stoichio- metric compounds have been applied to analyses of the Ti-C, Zr-C, Hf-C, NbC, Ta- C, Ti-O, Zr-O, Ti-N, and Zr-N systems. The thermodynamic framework, based on the SchottkyWagner model for non-stoichiometric phases has been applied to predict phase equilibria and vaporization data for these systems. Comparison with experimental thermodynamic, vapor pressure, and equilibria data available in the literature is very satisfactory. In addition, correlation between thermodynamic properties and vacancy concentration data where possible yields good agreement.
