Relationships between Fatigue Mechanical Properties and Roughness of Fatigue Fracture about 16MnR Steel after High Temperature

Abstract:

The microstructure of metal material would change with temperature, the roughness of the metal fracture would also vary. The mechanical properties of materials closely related to roughness of fracture. In this paper, after high temperature the crack strain fatigue fracture roughness and fatigue mechanical properties were analyzed for 16MnR steel. Further, relationships between roughness of fatigue fracture and temperature were also discussed.
