Dramatically improving thermoplasticity of FGH4096 superalloy by a novel sub-solvus temperature holding followed by extremely slow cooling

Dramatically improving thermoplasticity of FGH4096 superalloy by a novel sub-solvus temperature holding followed by extremely slow cooling

In this work, the thermoplasticity of hot extruded (HEXed) FGH4096 superalloy was greatly enhanced by sub-solvus temperature holding followed by extremely slow cooling (S-ESC). After S-ESC processing, the dispersed fine γ′ precipitates inside the grains and grain boundaries obviously grow up. Under...
