• A correlation factor fBB for matter transport by vacancies is simulated for the nearest-neighbour binding model of a very dilute face-centered cubic (FCC) alloy of impurity B in host A, which is called five-frequency model, in a Monte Carlo method. In the model, it is assumed that vacancy jumps involving nearest neighbours (n.n.) of the impurity are affected. Whereas vacancy jumps not involving n.n. of the impurity are not affected by the impurity. Simulated results by computer for the correlation factor are in good agreement with the analytical equation derived by Manning. The program made by Visual Basic (v.4) is userfriendly arranged and easy to handle for the present purpose.
