Abstract

The oxidation behavior of a Fe-20Cr-25Ni-Nb austenitic stainless steel was investigated in an oxidizing environment at 1000 °C. Results show that an accelerated oxidation occurs after a transition point and some oxide nodules with two layers are formed on the steel surface. The oxidation of intergranular Fe₂Nb phases can induce micro-cracks and promotes the formation of re-generated Cr₂O₃ phases. The formation and growth of the re-generated Cr₂O₃ phases are related to the cracking and spallation of the oxide scale, which result in the formation of these oxide nodules and the associative accelerated oxidation.
