Résumé

The oxidation behaviour of Fe-Cr-Al alloy in O2 was studied in the temperature range 800-1200°C for two types of sample: platelets and wires. In both cases the oxidation rate is controlled by a diffusion process. However, the induced growth stresses and their relaxation are very sensitive to the geometry of the oxidized sample. They have been evaluated as a function of time and temperature by following the resulting differences observed in the rate constants.
