Définition

The change in grain structure which occurs when the metal is annealed, during which the deformed grains, strain hardened by working, become new unstrained grains.

Rearrangement of the structure in a material in which the formation and growth of nuclei replace the original, often deformed crystals with new, tension-free crystals with reduced hardness but otherwise identical properties.

Note :

Heating at a condition long from equilibrum or strong deformation are each often sufficient to induce recrystallization.
