Advanced Steels

This lecture covers the fundamentals of steel metallurgy, an overview of high-performance steel classes, including stainless steels, steels for elevated temperature applications, and advanced high strength steels like AHSS, TRIP, and TWIP steels. It discusses the importance of steels, the steelmaking process, the Fe-C diagram, phases in steel, classification of steels based on alloy content and product types, alloying elements like Cr and Ni, and the heat treatment of steels. The lecture also delves into microstructures of carbon steels, the role of alloying elements, and the nomenclature of alloy steels. It concludes with a focus on single-phase and multi-phase microstructures, steel nomenclature, and the impact of heat treatment on steel properties.
