Diffusion in {beta}(B{sub 2}) and {beta}{prime}(bcc) Fe-Al alloys are of practical interest due to the potential applications at high temperatures. A review of available diffusion data for Fe-rich Fe-Al alloys at 1000 C indicates appreciable differences in the reported values of interdiffusion coefficients. Intrinsic diffusion coefficients and tracer diffusion coefficients are available for selected compositions and temperatures. In this paper are presented interdiffusion and intrinsic diffusion studies carried out at 1000 C with solid-solid diffusion couples assembled with Fe-Al alloys containing up to 50 at.% Al. Intrinsic diffusion coefficients were determined at marker compositions and were employed for an estimation of atomic mobilities and vacancy wind parameters on the basis of a random alloy model incorporating vacancy wind effect. Thermodynamic factors were also assessed at the marker compositions.
