摘要: In this paper, the low cycle fatigue (LCF) behaviour at 300 8C in air and liquid lead bismuth eutectic (LBE) of T91 martensitic steel is studied. From LCF tests range D3t 0.4–2.4%, it shown that cyclic stress response consists a softening. Monotonic stress–strain curves do not change with environment, whereas life reduced after high strain LBE compared to air. Metallographic fractographic observations suggest reduction resistance due metal enhancement crack propagation rate. q 2005 Elsevier Ltd. All rights reserved.
