Resumo
In the present research, the microstructure and oxidation behavior of an Fe-8.26Mn-5.25Si-12.80Cr-5.81Ni-
11.84Co shape memory stainless steel (SMSS) was studied at 800 °C in air for up to 120 h. Phase changes and
oxidation mechanism were discussed based on microscopy analyses, thermogravimetric measurements and
thermodynamic simulations. The results show that oxidation exposure promotes the formation of the σ, χ and
ferrite phases in the metallic substrate. The oxidation behavior follows a parabolic law, with the kinetics of
oxidation being controlled by the Mn2O3 oxide growth in the first hours, and by Mn3O4 and MnCr2O4 spinel
growth after 24 h of exposure.
