Webis divided into two stages: recovery and polygonization. Recovery, under the deformed metals heating, occurs in all cases, while polygonization takes place only under specific conditions. Recovery of the cold-worked metal is the stage of the return, when the quantity of the point defects, mostly vacancies, decreases; ... WebRecovery and dynamic recrystallization. Following Reference Montagnat and Duval Montagnat and Duval (2000), we assume that the dislocation density of each cell is balanced by three distinct processes, namely, production by work-hardening, reduction by grain-growth recovery and decrease by polygonization recovery, which are respectively …
