Features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts. Critically reviewed; contains basic and applied research results, a survey of current literature and other pertinent articles. Covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use. Includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. Updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
