The Journal of Phase Equilibria and Diffusion (JPED) is focused on the crystallographic, chemical, diffusion, and other kinetic properties of phases. It features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts, as well as critically reviewed basic and applied research results, and a survey of current literature. JPED 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. It includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics.
