Research on Fatigue Damage and Crack Propagation of GH4133B Superalloy Used in Turbine Disk of Aero-engine

摘要：

　　The fatigue damage and fracture of GH4133B superalloy used in turbine disk of aero-engine are studied.Firstly,the fatigue limit is measured,and the relation between electric resistance change ratio and number of fatigue loading cycles is investigated for smooth samples.
