“…FeCrAl exhibits a breakaway oxidation reaction due to the protective layer of Al2O3 forming below 1773 K, resulting in a change in reaction behavior that is modeled using two different temperature ranges for Equation (6). Below 1773 K, the FeCrAl oxidation rate is modeled [56], and above 1773 K the default oxidation data for stainless steel is used as once the Al2O3 shell fails, FeCrAl oxidation is dominated by FeO in the same manner as stainless steel. This approach has been widely used in past analysis with good results [52][54] [56].…”
