Explanation
The deformation processing above the crystallization temperature of the metal or alloy being deformation is called hot working. Including hot rolling, forging, hot extrusion, etc. Because metallic materials generally have the ability to easily deform with large deformation at high temperature - so most metal materials are subject to overheating plus I. To shape. Broadly speaking, hot working also includes foundry, heat treatment, weld, etc^
