Influence of surface nanocrystal on the interface reaction between Fe3Al and 1060Al alloy is investigated. A nanocrystal layer serving as interlayer was produced on Fe3Al by surface mechanical attrition. Then Fe3Al was diffusion bonded with 1060Al alloy at 873K. Surface microstructure of Fe3Al alloy after mechanical attrition is observed on X-ray diffractometer and transmission electron microscope. Atom diffusion and phase constitution at the diffusion interface is observed on scanning electron microscope and energy disperse spectroscope. Results show nanocrystal about 37nm in size is produced on Fe3Al alloy after 10min attrition. Microstructure and phase constitution at diffusion interface imply that atom diffusion is restrained at 873K because of the presence of nanocrystal.
