Thermodynamic Modelling of High Temperature Systems
Thermodynamic modelling is widely used to predict phase equilibria and solute partitioning in high temperature metals processing. There have been significant advances in computational thermodynamic modelling in the last three decades. A number of thermochemical software packages and databases have been established and developed, offering different features and capabilities. This paper will describe the basic fundamentals of thermodynamic modelling focused on multi-component phase equilibrium based on Gibbs energy minimization. Different thermodynamic packages used by the authors will be explained and key features highlighted. The packages considered are Chemix-Thermodata, MTDATA, FactSage, and HSC. Selected thermodynamic case studies involving the thermodynamic modelling of the magnesium production using these packages are also presented.
