Abstract A complex concentrated Co-Cr-Fe-Mn-Ni-Si alloy with increased configurational entropy and contents of Cr, Mn, and Si corresponding to those in 316L stainless steel was studied with respect to its oxidation behavior. Early-stage oxidation was investigated for annealing at 400 °C and 800 °C. In addition to Cr, considerable amounts of Fe, Co, and Ni were found in the oxide, and nodules formed at 800 °C. In contrast to 316L, on which a protective corundum-type oxide forms during oxidation, the formation of spinel-type oxide was observed to dominate both at low and high temperature.
