The mechanical deformation of material above its recrystallization temperature is known as what?

The mechanical deformation of material above its recrystallization temperature is known as hot working. This process involves shaping metals and alloys at elevated temperatures, which allows for significant plastic deformation without the material becoming too hard or brittle. At high temperatures, the atomic mobility increases, enabling dislocations to move more freely, thus allowing for easier shaping and reducing the risk of fracture.

Hot working is commonly used in various manufacturing processes, such as forging, rolling, and extrusion, where maintaining ductility is crucial for successfully forming materials into desired shapes. This allows for larger amounts of deformation compared to cold working, which occurs at or near room temperature and can lead to increased hardness and strength, but at a much lower degree of deformation capability.
