摘要：
Through oxide weight gain experiment, SEM and XRD analysis, the effects of Cr content were studied on the high-temperature oxidation behavior, the microstructures and phase compositions of oxidation scale of a high-manganese austenitic twinning-induced plasticity (TWIP) steel oxidized at 700 ℃ for 8 h. The results show that with increasing the Cr content, the anti-oxidation ability of this high-manganese austenitic TWIP steel increases. When the Cr content is 1.13 wt%, the mass gain of the steel oxidized at 700 ℃ for 8 h is about 30 μg/mm2, while the Cr content increases to 3.95 wt%, the mass gain decreases to 3 μg/mm2. Moreover, with increasing the Cr content, the compactness of oxide scale increases, and there are significant differences in the composition of oxide scales. © 2016, Editorial Department of Journal of Northeastern University.
