Effect of shot peening on the fatigue properties of nickel-based superalloy GH4169 at high temperature

This study investigates the influence of shot peening on the fatigue properties of GH4169 alloy at 20 °C, 350 °C and 650 °C in air. Work hardened layer with nanocrystals and deformation twins was generated in GH4169 surface after shot peening. Nanocrystallization process of microstructures was deepl...
