英文摘要	In this work, the high-temperature oxidation behavior of SIMP and commercial T91 steels was investigated in air at 800 A degrees C for up to 1008 h. The oxides formed on the two steels were characterized and analyzed by XRD, SEM and EPMA. The results showed that the weight gain and oxide thickness of SIMP steel were rather smaller than those of T91 steel, that flake-like Cr2O3 with Mn1.5Cr1.5O4 spinel particles formed on SIMP steel, while double-layer structure consisting of an outer hematite Fe2O3 layer and an inner Fe-Cr spinel layer formed on T91 steel, and that the location of the oxide layer spallation was at the inner Fe-Cr spinel after 1008 h, which led the ratio between the outer layer and the inner layer to decrease. The reason that SIMP steel exhibited better high-temperature oxidation resistance than that of T91 steel was analyzed due to the higher Cr and Si contents that could form compact and continuous oxide layer on the steel.; In this work, the high-temperature oxidation behavior of SIMP and commercial T91 steels was investigated in air at 800 A degrees C for up to 1008 h.
