It was hypothesised that it may be much easier to develop a protective film on nanocrystalline Fe-Cr alloys. However, successful processing of nanocrystalline alloy samples suitable for oxidation/corrosion testing proved to be a non-trivial task. This paper will present description of the processing of nanocrystalline Fe-Cr alloy powders by mechanical alloying. Powders this produced were successfully compacted and sintered to nearly 100% density while retaining nanocrystalline structure. When oxidation and aqueous corrosion resistance of nanocrystalline and microcrystalline alloys of same composition were compared, the nanocrystalline structure was found to provide in excess of an order of magnitude superior oxidation/corrosion resistance.
