Fatigue fracture mechanism of Ni-base superalloy GH4065A at elevated temperatures

Fatigue fracture mechanism of Ni-base superalloy GH4065A at elevated temperatures

GH4065A is a newly developed high-performance cast-wrought Ni-base superalloy with ultra-low C and N content used for advanced turbine engine disc. In this study， the alloy’s inclusions of the alloy are characterized and statistically analyzed. To investigate the fatigue fracture mechanism， strain-c...
