Nanostructured surface layer and high-cycle fatigue behavior at 850 °C of single-crystal nickel superalloy induced by surface grinding treatment

The microstructures in the surface layer by surface grinding treatment (SGT) and their fractographic features in high-cycle fatigue (HCF) at 850 °C are investigated for single-crystal nickel superalloy (SCNS) DD6. All samples after SGT show the nanostructure transition from singl...
