Abstract

The interdiffusion coefficient is related via the modified Darken equation to the tracer diffusivities of the constituents. The thermodynamic factor Φ entering the Darken equation for the interdiffusion coefficient is expressed in terms of the energy parameters which describe the ordering process in the binary alloy. Our calculations for Fe-Al alloys yield the dependence of Φ on the long-range order parameter. These calculations are performed with the parameters extracted from diffuse X-ray scattering data on FeAl.
