 Abstract
Fe-2%Mn-0.5%Si alloys were corroded at 600, 700 and for up to 70 h in 1 atm of gas, or 1 atm of -mixed gases, or 1 atm of -mixed gases. Oxidation prevailed in and gases, whereas sulfidation dominated in gases. The oxidation/sulfidation rates increased in the order of gas, gases, and, much more seriously, gases. The base element of Fe oxidized to and in and gases, whereas it sulfidized to FeS in gases. The oxides or sulfides of Mn or Si were not detected from the XRD analyses, owing to their small amount or dissolution in FeS. Since FeS was present throughout the whole scale, the alloys were nonprotective in gases.
