“Fundamentals of Engineering Metallurgy” provides a comprehensive introduction to the principles and application’s of metallurgy, essential for engineering students and professionals. The book begins with a detailed overview of metallurgy, including its definition, historical development, classification of metals and alloys, and its importance in engineering. It explores deeply into the atomic structure and bonding in metals, exploring crystal structures, lattice defects, phases, and phase diagrams to lay the groundwork for understanding metallic properties. The book comprehensively covers the mechanical properties of metals, including stress-strain relationships, tensile, compression, and shear properties, hardness, toughness, as well as fatigue and creep. Thermal properties are examined through discussions of heat capacity, thermal expansion, and conductivity, with a focus on how temperature affects metallic properties and the phenomena of thermal shock and fatigue. Phase transformations are explored in detail, including iron-carbon equilibrium diagrams, TTT and CCT diagrams, and heat treatment processes such as annealing, normalizing, quenching, and tempering. The book also discusses metallurgical processes, including metal extraction, pyrometallurgy, hydrometallurgy, refining, alloy formation, and powder metallurgy. Corrosion and corrosion of metals are discussed, highlighting fundamental concepts, types of corrosion, prevention methods, and material selection for corrosion resistance. Advanced techniques are covered, including metallography, electron microscopy, X-ray diffraction, surface engineering, coating techniques, and applications of nanostructured materials. Overall, “Fundamentals of Engineering Metallurgy” serves as an essential resource for understanding fundamental concepts and advanced techniques in metallurgy.
