Description: In this paper, we review the progress that has been made with analytical random-walk calculations in understanding tracer and chemical diffusion in intermetallics. Computer simulations of diffusion are not discussed unless they have been used for the testing of analytical results. For both tracer and chemical diffusion phenomena we review three types of approaches to diffusion kinetics: these are 1) explicit atom-vacancy exchange frequencies given, 2) atomic interactions given (Ising alloy models), and 3) six-jump-cycles used as the units of diffusion.
