Engineering Metallurgy is a meticulously crafted textbook designed to provide mechanical and aeronautical engineering students with a foundational and advanced understanding of metallurgical science. Authored by a team of experienced academic professionals, this book bridges theoretical metallurgy with practical engineering applications. The content spans from the microscopic crystal structure of metals to macro-level material behavior, including detailed analysis of alloys, phase diagrams, heat treatment, and surface hardening processes. Each chapter introduces key concepts such as crystallography, solid solutions, iron-carbon equilibrium, and thermal processing with clarity and structured progression. Special emphasis is placed on the influence of microstructure on mechanical properties, solidification behavior, and modern surface treatment techniques. With its integration of scientific principles, engineering insights, and visual aids, Engineering Metallurgy serves as both an academic textbook and a practical reference for students, educators, and professionals engaged in material selection, failure analysis, and manufacturing processes.
