The current state of understanding of emerging iron alloys and high-alloy ferrous systems, in comparison with some conventional steels, is compiled in this single volume to further their development. While most of the conventional steels are produced routinely today, many advanced high strength steels and iron-based alloys are still in the laboratory stage. The iron-based emerging alloys can yield high levels of mechanical and physical properties due to their new alloy concepts and novel microstructures leading to multiple benefits of their use in terms of sustainability and environmental impact. This book contains introductory chapters that present the requisite background knowledge on thermodynamics, phase diagrams, and processing routes used for the ferrous alloys to enable the readers a smooth understanding of the main chapters. Then, an overview of the conventional microalloyed steels and advanced high strength steels is given to present the benchmark of the existing steels and ferrous alloys manifesting their current state-of-the-art in terms of physical metallurgy and engineering applications. Subsequent chapters detail novel, emerging ferrous alloys and high-alloy ferrous systems. Summarizes the state-of-the-art of emerging iron-based alloys and the new processing and physical metallurgy-related developments of high-alloy iron systems;Explores new iron-based systems driven by the need for new properties, enhanced performance, sustainable processes and educed environmental impact;Compiles cutting-edge research on the progress of materials science of iron-based systems, from physical metallurgy to engineering applications, and possible avenues for future research.

Diffusion in Ferrous Alloys

The Structures of Alloys of Iron: An Elementary Introduction provides an elementary review of some of the factors affecting the structures of alloys of iron, with examples illustrating points of interest. In view of the existence of books dealing with the technology and properties of iron alloys it was decided that the present book should be concerned only with the structures, and not with the properties of the alloys. In connection with steels it was thought best, in the space available, to deal only with those based on iron-carbon alloys. The book begins with chapters on the metal iron, the crystal structures of iron, the diffusion of iron and its alloys, and the intermetallic chemistry of iron. Subsequent chapters deal with the structure of steels, plain carbon steels, the structure of alloy steels, and cast irons. This book is intended for those wanting to make a general survey of the subject before undertaking a detailed study. The reader must understand clearly that much further work will be necessary before he can hope to understand properly even one class of the alloys of industry.
