Abstract
The kinetic parameters of recrystallization (nucleation rate and the growth of recrystallization nuclei) in aluminium (99·85%) were investigated on specimens subjected to deformation of 12, 19, 23, and 44% by simple tension and by wire-drawing. Some of the specimens underwent high temperature recovery before recrystallization. The previous recovery has delayed the onset and the maximum of nucleation, has reduced the migration velocity of the boundaries of recrystallized regions, and has slowed down the recrystallization kinetics. The previously recovered specimens yielded finer grains upon the completion of primary recrystallization. A mechanism is proposed by which recovery brings about these structural changes during recrystallization.
