Automotive Steels: Design, Metallurgy, Processing and Applications explores the design, processing, metallurgy, and applications of automotive steels. While some sheet steels are produced routinely in high volume today, there have been significant advances in the use of steel in the automotive industry.
This book presents these metallurgical and application aspects in a way that is not available in the current literature. The editors have assembled an international team of experts who discuss recent developments and future prospects for automotive steels, compiling essential reading for both academic and industrial metallurgists, automotive design engineers, and postgraduate students attending courses on the metallurgy of automotive materials.
Presents recent developments on the design, metallurgy, processing, and applications of automotive steels
Discusses automotive steels that are currently in the early stages of research, such as low-density and high modulus steels that are driving future development
Covers traditional steels, advanced high strength steels, elevated Mn steels and ferrous composite materials
Metallurgical engineers, process and design engineers
