Some interactions between creep and fatigue in a 1% CrMoV steel

Studies have been made of interactions between creep and fatigue by considering the effects of prior fatigue on creep, and of prior creep on high strain fatigue, in a 1% CrMoV steel at 838 K. null Prior fatigue enhanced steady-state creep rates and reduced fracture lives, although these effects decreased with lower creep stresses. This has been explained on the basis that the cyclic softening which the material undergoes during high strain...
