Recrystallization temperature is the minimum temperature at which a deformed metal will undergo recrystallization, forming new grains without any prior strain. This process is crucial in metallurgy for restoring ductility and reducing internal stresses in metals after cold working.

Recrystallization is a process used in metallurgy and materials science to eliminate defects and refine grain structures in metals by heating them to a specific temperature, allowing new grains to form without changing the phase. This process enhances mechanical properties like ductility and toughness while reducing internal stresses and dislocations within the material.

Metallurgy is the branch of science and technology concerned with the properties of metals and their production and purification. It involves processes such as extraction, alloying, and heat treatment to manipulate the physical and chemical properties of metallic elements and compounds for various applications.

Reducing internal stresses

Cold working is a metalworking process where metals are deformed below their recrystallization temperature, enhancing strength and hardness through strain hardening. This technique improves mechanical properties without altering the material's chemical composition, making it ideal for applications requiring precise dimensional accuracy and high surface finish.
