摘要：

Time-dependent creep deformation at crack tip in SUS304 stainless steel and its effects on fatigue crack growth has been investigated. The deformation attributes to the occurrence of room temperature creep at the crack tips under constant stress intensity factor. The deformation increases with the increasing of stress intensity factor. Comparing with single wave overload, retardation is more obvious after room temperature creep, and the retardation is related with overload ratio when room temperature creep occurs.
