Abstract
vVe considered two different mechanisms by which a vacancy diffuses from one
stable state to the next within a sublattice for a two dimensional binary alloys. For
both mechanisms, we have found that the diffusion time is a function of jumping
probabilities which in tmn depend on energy barriers and lattice spacing. vVe
compared the diffusion times for the two mechanisms and identified conditions
under which one is favored over the other
