Collective and tracer diffusion kinetics were considered for the case of a ternary random alloy. A formal solution from the self-consistent theory of Moleko et al was derived for collective diffusion and compared with the corresponding solution for the binary random alloy. Tracer diffusion in the ternary alloy was treated from the perspective of a special case of the quaternary random alloy. Results from Monte Carlo calculations for tracer and collective correlation factors (for the body-centered cubic ternary random alloy) were found to be in excellent agreement with this self-consistent theory but in only semi-quantitative agreement with the earlier theory of Manning.
