Abstract
A general expression is derived for the vacancy-wind factor which occurs in the equation linking the intrinsic diffusion coefficient, the tracer diffusion coefficient, and the thermodynamic factor in a binary substitutional alloy. The expression leads immediately to the binary analogue of the exact Nernst-Einstein equation derived recently by Murch in the unary system. A realization by Monte Carlo computer simulation of the expression was made for the random-alloy model. The results obtained were in excellent agreement with the results of the analysis by Manning.Keywords
