A stability criterion for deformation and deposition textures of metals during annealing

Abstract

Deformation and electrodeposition textures of metals can or cannot change during annealing. When the textures change, the annealing textures are sure to be the recrystallization textures, because the formation and migration of high-angle boundaries driven by the energy stored during fabrication take place during annealing. When the textures do not change, metals can undergo recovery or recrystallization. Recovery includes all processes releasing stored energy that do not require the movement of a high-angle grain boundary. Typically, recovery processes involve the rearrangement of dislocations to lower their energy, e.g., by the formation of low-angle subgrain boundaries. A criterion for the texture remaining unchanged during annealing is discussed, whether recrystallization or recovery.
