Abstract
In this study, preoxidations of a Y2O3-dispersed FeCrAlFi alloy (MA956) were done in 1atm of dry, flowing O2 for 2hr at 1000°C. Weight gains were measured during oxidation using Cahn 1000 microbalance and after oxidation using a Mettler AE163 balance. SEM observations of the scale surface before and after exposure to the O-S environment indicated almost no change in the scale surface morphology. TEM samples were made parallel to the sample surface near the oxide-gas interface and near the metal-oxide interface to study the possible penetration of sulfur into the preoxidized scale by cracks or grain boundaries. The samples were analyzed in a FEG-STEM equipped with XEDS.
