Steels: Structure, Properties and Design 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 materials, possessing a wide range of structures and properties. By examining the properties of steels in conjunction with structure, the 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 revised and updated with 2 new chapters, expanded content throughout,and yet it retains its clear writing style, extensive bibliographies, and real-life examples. One of the new chapters deals with the additive manufacture of steels with a focus on structure and properties. The other has visionary applications of steel that lead to a dramatic reduction of the carbon dioxide burden, within a short period of time, and without compromising the quality of life that depends on steels.
