Advanced Steels: Properties and Applications

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. It discusses the history, properties, and microstructures of advanced high strength steels, as well as the influence of Mn content on their properties. The lecture also explores TRansformation-Induced Plasticity (TRIP) and Twinning-Induced Plasticity (TWIP) steels, their mechanical properties, and the role of stacking fault energy on the deformation mechanism. Furthermore, it delves into the applications of Advanced High Strength Steels in modern car body structures, emphasizing their lightweight, safety, design flexibility, and sustainability through recycling.
