ResumoAn Fe–31.8Mn–6.09Al–1.60Si–0.40C alloy was subjected to thermogravimetric tests, in atmospheres of pure oxygen and synthetic air. The alloy showed good oxidation resistance, especially at 600 and 700 °C in air and at 600 °C in oxygen. Owing to autocorrelation identified in the results, kinetic data were analyzed by the statistical method of Cochrane and Orcutt. Parabolic kinetic behaviour was observed for the Fe–Mn–Al–Si–C alloy oxidation process in air at 600, 700 and 800 °C and in pure oxygen at 900 °C.
