This lecture covers the different phases present in carbon steel alloys, the lever arm rule to determine phase proportions, equilibrium diagrams to understand phase compositions, and the formation of different microstructures like martensite, bainite, and perlite during cooling. It also discusses the effects of carbon content on steel properties, the concept of eutectoid and peritectic reactions, and the transformation of austenite into different phases. The instructor explains the competition between phase change driving force and diffusion, the morphology of martensite, and the use of high-strength multiphase steels in modern applications.
