英文摘要	Corrosion tests of T91 were carried out in the stagnant lead-bismuth eutectic (LBE) containing 10(-6), 10(-7), and 10(-8) wt% oxygen at 500 degrees C for up to 2000 h, respectively. The dependence of corrosion characteristics on oxygen concentrations in LBE was obtained. The results show that the oxide-scale structure changes from a three-layer magnetite/spinel/internal oxidation zone (IOZ) scale under the oxygen concentration of 10(-6) wt%, to the formation of a two-layer spinel/IOZ scale under the oxygen concentrations of 10(-7) and 10(-8) wt%. In addition, with the decrease of the oxygen concentration, the Cr/Fe ratio in the Fe-Cr spinel slightly increases in a linear rule while the thicknesses of the oxide layers gradually decrease.
