Influence of Cooling Holes Distribution on High Cycle Fatigue Fracture Behavior of DD6 Single Crystal Superalloy

The modeling air-cooled turbine blades specimens of DD6 single crystal superalloy with different distributions of cooling film holes were used to study the high cycle fatigue properties at room temperature. The SEM fracture observation was carried out. The results indicate that the cooling holes hav...
