Abstract
Oxide dispersion strengthened FeCrAl alloys are of great interest for fossil energy applications because of their superior oxidation and creep resistance at very high temperature (1200°C). The durability of these alloys in air is known to depend on two critical parameters: the total Al reservoir and the rate at which Al is consumed because of oxidation. Two ODS FeCrAl alloys have been thermally cycled at T > 1100°C in industrially relevant atmospheres rich in H2O and CO2. The effect of the environment on the onset of breakaway oxidation was assessed, and lifetime models were adjusted according to each specific atmosphere.
