270121 VO Thermodynamic models and phase diagram optimization (2012W)

The lecture gives an overview about the use of thermodynamic models for the assessment of phase diagrams. Content: The connection of thermodynamics and phase diagrams - critical assessment of experimental data - empirical and physical models - modelling of the Gibbs energy - the SGTE format for the parameterization of thermodynamic data - modelling of the concentration dependence of the thermodynamic functions in solutions - Redlich Kister polynomials - the compound energy model - phase diagram optimization: the CALPHAD method - computer programs for the calculation of phase diagrams - practical examples.
