Steels: Structure and Properties, Fourth Edition is an essential text and reference, providing indispensable foundational content for researchers, metallurgists, and engineers in industry and academia. The book provides inspiring content for undergraduates, yet has a depth that makes it useful to researchers. Steels represent the most used metallic material, possessing a wide range of structures and properties. By examining the properties of steels in conjunction with structure, this book provides a valuable description of the development and behavior of these materials-the very foundation of their widespread use. The new edition has been thoroughly updated, with expanded content and improved organization, yet it retains its clear writing style, extensive bibliographies, and real-life examples. Contains a new chapter on nanostructured steels, with new content integrated into an existing chapter to describe the physical metallurgy of coatings, surface treatments, and multivariate high-performance steels Includes derivations with important equations so that students from a broad range of subjects can appreciate the issues without being bogged down in mathematics Presents new micrographs and figures that reflect the resolution and capabilities of modern instruments
