Lecture
This lecture covers the properties and applications of carbon steels, including the different types of steel based on carbon content and alloying elements. It explains the mechanisms of grain refinement and how they contribute to the strength and ductility of the material. The lecture also discusses the transition from ductile to brittle behavior in carbon steels, influenced by factors such as grain size and composition. Additionally, it explores the impact of impurities on steel properties and the role of microalloying elements in enhancing strength and toughness.
