Thermodynamic Modeling: Real Solutions

This lecture delves into thermodynamic modeling of real solutions in materials science, focusing on regular and sublattice models. It covers the Gibbs energy function, enthalpy of mixing, and binary interaction parameters. The lecture also discusses the quasi-chemical approach, entropy and enthalpy terms, and extrapolation to higher-order systems. Various examples and phase stabilities are analyzed, along with the influence of interaction parameters. The lecture concludes with a detailed exploration of thermodynamic databases for steel and Fe-alloys, providing insights into elements, systems, phases, and properties.
