Revised to reflect recent developments in the field, Phase Transformation in Metals and Alloys, Fourth Edition, continues to be the most authoritative and approachable resource on the subject. It supplies a comprehensive overview of specific types of phase transformations, supplemented by practical case studies of engineering alloys. The book's unique presentation links a basic understanding of theory with application in a gradually progressive yet exciting manner. Based on the authors' teaching notes, the text takes a pedagogical approach and provides examples for applications and problems that can be readily used for exercises.NEW IN THE FOURTH EDITION 40% of the figures and 30% of the text Insights provided by numerical modelling techniques such as ab initio, phase field, cellular automaton, and molecular dynamics Insights from the application of advanced experimental techniques, such as high-energy X-ray diffraction, high-resolution transmission electron microscopy, scanning electron microscopy, combined with electron backscattered diffraction New treatment of ternary phase diagrams and solubility products The concept of paraequilibrium in systems containing highly mobile interstitial elements Thermodynamics of grain boundaries and the influence of segregation on grain boundary diffusion Reference to software tools for solving diffusion problems in multicomponent systems Introduction to concepts related to coincident site lattices and methods for determining the dislocation content of grain boundaries and interfaces Updated treatment of coherency and interface structure including the important fcc-bcc interfaces Treatment of metallic glasses expanded to cover critical cooling rate Austin-Rickets equation introduced as an alternative to the Avrami equation in the case of precipitation kinetics Discussion of the effects of overlap in nucleation, growth and coarsening Discussion of pearlite and bainite transformations updated Entirely new and extensive treatment of diffusionless martensitic transformations covering athermal and thermally activated martensite in ferrous systems as well as shape memory, superelasticity and rubber-like behavior in ordered nonferrous alloys <
