Abstract

Previous findings demonstrated roughness increase in the oxide/ferritic Mn-depleted zone interface in an austenitic FeMnSiCrNi shape memory stainless steel (SMSS) cyclic oxidized, generated by plastic deformation. The main aim here was to assess the causes of roughness evolution during cyclic oxidation of an FeMnSiCrNiCe SMSS at 950 degrees C. Thus, isothermal and cyclic oxidation tests were conducted, metal/oxide interface roughness was measured and the oxide layers characterized. The isothermal tests on the FeMnSiCrNiCe SMSS samples demonstrated increasing roughness, however less than after cyclic tests, allowing the identification of a more complete mechanism, where oxide growth and chemical effects also take place.
