摘要	Low cycle fatigue behavior of T91 steel was investigated in oxygen saturated liquid lead-bismuth eutectic (LBE) at 550 degrees C with different strain rates. The fatigue life of T91 steel decreases by about 85 % with decreasing strain rate from 0.4 % to 0.004 %/s. The crack tip was carefully analyzed by advanced characterization. The intergranular oxidation resistance of T91 steel decreases at lower strain rates, leading to fatigue failure mode changes from quasi-cleavage to cleavage cracking. Notably, the cracks (>200 mu m) propagate along the recrystallization grain boundaries with Pb/Bi segregation but without oxides detected at 0.004 %/s.
