The Thermodynamic Modeling of Multicomponent Phase Equilibria



Ursula R. Kattner


The present paper gives an overview of the CALPHAD method and recent progress made. First a brief history is given then the scope of phase diagram calculations is described. Thermodynamics descriptions most commonly used in the CALPHAD method are described and the methods used to obtain the numerical values for these descriptions are outlined. The extrapolation of higher-component systems is explained and recent progress in the quality of assessments is demonstrated. A brief overview of available computer software tools and databases is given. Finally, the application of phase diagrams calculations is demonstrated for a few examples.
