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.
