Modern Physical Metallurgy, Third Edition discusses the fundamental principles of physical metallurgy and demonstrates how the application of the principles leads to a clearer understanding of many technologically important metallurgical phenomena. This book covers the substantial developments in the microstructural examination of metals using X-ray microanalysis, strengthening of metals, and surface and interface behavior. Numerical problems on crystallography, constitution and microstructure, diffraction, diffusion, defect theory, and thermodynamics are also provided in this publication. This edition is useful for all undergraduate degree courses in metallurgy and materials in both universities and polytechnics. The large range of topics included, from superconductivity to superplasticity and from macroscopic plasticity to fracture toughness, gives students sufficient background to the fundamental principles and practical details for examination requirements.
