Calculations were made of the thermodynamic factor, F, in the Darken equation for interdiffusion. The factor, F, was expressed in terms of the energy parameters which described the ordering process in the alloy. The calculations for Fe-Al revealed a dependence of F upon the long-range order parameter.
