Abstract
Low-cycle fatigue properties of 30Cr1Mo1V steam turbine rotor steel were studied by RDL05 electronic creep fatigue test machine at 0.1%.s-1, 0.3%.s-1, 0.5%.s-1 loading rates applied the total strain controlled method. The results involve that with the loading rate increases at 538°C, cyclic stress of the rotor steel increases, and low-cycle fatigue life increases too; in the same strain range values, the increasing loading rate leads to the greater stress amplitude; with the increase of the strain range values, the stress increases and the low-cycle fatigue life decreases. The relationship of stress-strain and the loading rate is ▪, the relationship of low-cycle fatigue life and the loading rate is ▪.
