Fatigue life and initiation mechanisms in wrought Inconel 718 DA for different microstructures

摘要：

　　Wrought Inconel 718 DA superalloy disk zones present a wide range of behavior in fatigue life due to the variability of the microstructure.In order to link the effect of the forging conditions and achieved microstructure to the fatigue life,two microstructures have been tested in fatigue.
