| Abstract | |
The relationship between alloy chemical composition and oxidation behavior of austenitic Fe-Mn-Si-Cr-Ni shape memory stainless steels (SMSSs) during exposure at 800 degrees C in air was investigated. Although high Si and Cr additions are beneficial for both the shape memory effect and oxidation resistance, the increase of these ferrite stabilizer elements in Fe-Mn-Si-Cr-Ni SMSSs makes the oxidation-induced ferrite stable at the early stages of the oxidation exposure, which in turn allows a faster diffusion of Mn, controlling the kinetics of oxidation. Our results suggested that the austenite stability should be maintained during the oxidation process for higher performance of these materials. (AU) | |
