Cold processsing will not advance to the adapted effect. Access such as abbreviation the ductility and balance stress. Because the apparatus of algid alive or plan hardening is the access of break density, so any can be rearranged or processing adjustment for eliminating dislocations can annihilate aftereffect of algid processing. Action annealing is a calefaction analysis method, acclimated to annihilate some or all of the aftereffect of algid processing. Action annealing is disconnected into three stages: accretion ( Accretion ), recrystallization and atom advance ( Recrystallization ) ( Atom Advance ). Accretion occurred at low temperature. It can annihilate the balance accent after alteration the break density. Recrystallization occurs at abstinent temperature. Heating aloft a assertive temperature, the new atom absolute actual low break body in the atom abuttals will generate. Due to the amount of dislocations is abundantly reduced, the recrystallization of the metal will accordingly reduces the strength, ductility increased. Heating the temperature continues to rise, to the atom advance stage. At this stage, all the algid processing aftereffect is eliminated. So this date is not expected.
