What Is Recrystallization?

Recrystallization

Recrystallization of steel is a metallurgical process where deformed grains within the steel are replaced by a new set of defect-free grains. This process typically occurs during or after heat treatment, where the steel is heated to a specific temperature range, usually between 550 and 700 degrees Celsius. The new grains nucleate and grow, consuming the old, deformed grains, which results in a reduction in the steel's strength and hardness while increasing its ductility. Recrystallization is essential for restoring the steel's microstructure after it has been work-hardened through processes like rolling or bending.
