Training Manual . - M. : Metallurgy, 1978. — 248 s. The manual consistently describes various ways to describe the process of diffusion of atoms in metals, methods for determining the appropriate coefficients, physical bases and mechanisms of the process. A significant place in the manual is given to the influence on the rate of diffusion of temperature and electric fields, the features of diffusion in multiphase systems, as well as the role of diffusion in the processes of production, operation and destruction of metals. The textbook is intended for students specializing in the field of metal physics, metal science and physical and chemical studies of metallurgical processes (specialties 0405, 0406, 0407) . It can also be useful for students of other material sciences specialties, graduate students, researchers and engineers working in the metallurgical, aviation and engineering industries ..
