Thermodynamic Modeling: Ge-Ni System

This lecture covers the thermodynamic modeling of the Ge-Ni binary system, focusing on the assessment of phase diagrams, enthalpy of mixing, and Gibbs energy. It discusses the CALPHAD method, ideal and regular solutions, and real solutions, including the sublattice model. The lecture also presents examples of Gibbs energies of phases in pure iron, stoichiometric compounds, and the influence of interaction parameters on phase stabilities. Various models and approaches for thermodynamic assessment are explored, along with comparisons between simulation and experimental data.
