Abstract

Nanocrystalline and microcrystalline Fe-10Cr alloys were prepared by high energy ball milling followed by compaction and sintering and then oxidized in air for 52 hours at 350°C. The oxidation resistance of nanocrystalline alloy as determined by measuring the weight gain after regular time intervals was compared with that of the microcrystalline alloy of similar chemical compositions, prepared by similar processing route and oxidized in similar conditions. Oxidation resistance of nanocrystalline Fe10Cr alloy was found to be an order of magnitude higher than that of microcrystalline Fe10Cr alloy. The paper also presents results of secondary ion mass spectrometry of oxidised samples of nanocrystalline and microcrystalline Fe-Cr alloys, evidencing the formation of a much protective oxide scale of the nanocrystalline alloy.
