The Journal of Phase Equilibria and Diffusion (JPED) focuses 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 also offers information on such phenomena as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics.

《相平衡與擴散雜志》（JPED）關注相的結晶、化學、擴散和其他動力學性質。它的特點是，國際專家對科學和工業上重要的合金系統進行了關鍵相圖評估，并對基礎和應用研究結果進行了批判性審查，并對現有文獻進行了綜述。JPED涵蓋了相圖的重要性以及相圖準備和使用的新研究技術、設備、數據評估、命名、表示和其他方面。它還提供了有關平衡的動力學控制、相干效應、雜質效應以及熱力學和晶體學特性等現象的信息。
