Hot working
Any metal shaping process occurring above its recrystallization temperature / From Wikipedia, the free encyclopedia
In metallurgy, hot working refers to processes where metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the material to recrystallize during deformation. This is important because recrystallization keeps the materials from strain hardening, which ultimately keeps the yield strength and hardness low and ductility high.[1] This contrasts with cold working.
Many kinds of working, including rolling, forging, extrusion, and drawing, can be done with hot metal.
