Conventional wisdom says that “hot working” means that the metal is deformed or worked at an elevated temperature … however, technically “hot working” means that:.

Metalworking Processes. Temperature in metal forming. For any metal, the values of K and n depend on temperature. Strength and strain hardening are both reduced at higher temperatures. These property changes are important because they result in lower forces and power during forming. In addition, ductility is increased at higher temperatures, which allows greater plastic deformation of the work metal. For these reasons the forming processes can be classified as:. Working of metal above recrystallization temperature. Working of metal below recrystallization temperature. Improves . mechanical properties such as ductility and malleability. Strength and hardness increases, but reduces ductility. A material is pushed or drawn through a die of the desired cross-section.. Extrusion.  is a process used to create objects of a fixed cross-sectional profile. . Direct Extrusion. Indirect Extrusion.
