Recrystallization and the Development of Abnormally Large Grains After Small Strain Deformation in a Polycrystalline Nickel-Based Superalloy

The formation of abnormally large grains has been investigated in the polycrystalline nickel-based superalloy Rene 88DT. Cylindrical specimens with a 15 μm grain size were compressed to plastic strains up to 11.0 pct and subsequently rapidly heated to above the γ′ solvus at 1423 K (1150  null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null...
