Grain Refinement of a Powder Nickel-Base Superalloy Using Hot Deformation and Slow-Cooling
A pre-hot-deformation process was applied for a polycrystalline nickel-base superalloy to active deformation twins and dislocations, and subsequent slow cooling treatment was used to achieve grain refinement and microstructure homogenization. The microstructural evolution of the alloy was investigat...
