Current issues in recrystallization: A review

Abstract

Summary The authors have agreed that recrystallization is theformation of a new grain structure in a deformed material by the formation and migration of high angle grain boundaries driven by the stored energy of deformation. High angle grain boundaries are those with greater than a 10 to 15° misorientation. Recovery can be defined as all annealing processes occurring in deformed materials that occur without the migration of a high angle grain boundary. Grain coarsening can in turn, be defined as processes involving the migration of grain boundaries when the driving force for migration is solely the reduction of the grain boundary area itself. These definitions are consistent with some earlier definitions.
