Heteroepitaxial Recrystallization , a New Recrystallization Mechanism in Sub-Solvus Forged γ-γ ’ Nickel-Based Superalloys With Low Lattice Mismatch

A new dynamic recrystallization mechanism has recently been reported in -' Nickelbased superalloys after hot-forging in the sub-solvus domain. The mechanism leads to recrystallized grains encompassing a primary ' precipitate having the same crystallographic orientation. The nucleation of those grains actually occurs before deformation by inverse… CONTINUE READING
