Lecture
This lecture covers the fundamentals of phase diagrams, including unary, binary, ternary, and quaternary systems, as well as the Gibbs phase rule. It also discusses the lever rule, nucleation, growth, diffusion, and various phase transformations in alloys, such as diffusive and displacive transformations. The importance of solidification in alloy processing and the microstructures that result from different solidification conditions are also explained.
