Oxidation of a Dispersion-Strengthened Powder Metallurgical FeCrAl Alloy in the Presence of O2 at 1,100°C: The Influence of Water Vapour
Journal article, 2015

The oxidation behaviour of the FeCrAl alloy Kanthal(A (R)) APMT in O-2 + N-2 and O-2 + N-2 + H2O environments at 1,100 A degrees C was investigated using thermogravimetry and detailed analyses of the scale morphology with SEM/EDX and STEM/EDX. Wrought FeCrAl alloy Kanthal(A (R)) AF was used as a reference. Exposure time was up to 168 h. Water vapour influenced the early oxide growth kinetics. This effect is explained in terms of water acting as an oxidant, simultaneously with O-2. During later stages of the exposures, H2O had no effect on the kinetics of oxidation.
