NITRIDATION EFFECTS ON THE OXIDATION MECHANISMS OF AN ODS FeAl INTERMETALLIC ALLOY
Résumé
An ODS FeAl intermetallic alloy has been nitrided at low-energy high flux implantation diffusion leading to the formation of hexagonal AlN and α-Fe segregation. Its high temperature behaviour is subsequently evaluated under isothermal oxidation at 800º C. Microscopy techniques (SEM, TEM) will show that nitridation hinders aluminium outward diffusion and enhances iron outward diffusion giving rise to a layered structure.
