Flow Stress Evolution of P/M Nickel-base Superalloy During High-temperature Plastic Deformation

Abstract In this work, the use of scanning electron microscopy, transmission electron microscopy, electron backscatter diffraction technique and experimental study of the nickel-base superalloy FGH96 recrystallization behavior of alloy. Through experimental study found that the thermal deformation, FGH96 alloys under different plastic deformation at high temperature deformation process parameters, mainly dynamic softening and strain hardening in two stages.
