Diffusion via the agency of vacancies in a sc binary alloy with long- and short-range order was simulated using a Monte Carlo method. Results for the vacancy-wind factor occurring in the Darken relation connecting the intrinsic diffusivity, the tracer diffusivity and the thermodynamic factors were collected over the entire composition range at six temperatures. The results obtained were in excellent agreement with Manning's expression, which was exact for the random alloy, substituted with previously obtained computer-simulated values of the tracer diffusivities.
