Abstract
ABSTRACTThis work focused on the effect of holding duration at maximum and minimum stress on creep fatigue (CF) interaction of P92 steel based on load-controlled CF tests and conventional creep test at 873K. The mechanical testing results, CF cyclic strain and mesoscopic fracture morphology were analysed in this paper. Comparing with the pure creep damage, the results show when the load is held at the minimum stress, the fatigue load promotes creep damage, and when the load is held at the maximum stress, the fatigue load inhibits the creep damage. These results are also verified by CF interaction parameter μ. It can be explained by the CF interaction parameter μ to show whether the introduction of fatigue load promotes or inhibits creep damage.
