Phase Diagrams: Constituents and Phases

This lecture covers the concept of phase diagrams in materials science, focusing on binary and unary systems. It explains the relationship between temperature, composition, and the phases present in a system. The lecture also delves into the calculation of molar and mass compositions, the Gibbs phase rule, and the enthalpy of state changes. Additionally, it discusses the characteristics of diffusion in materials and the activation energy involved. The instructor provides insights into the behavior of different phases in unary systems and the energy transformations during state changes.
