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 … See more The lower limit of the hot working temperature is determined by its recrystallization temperature. As a guideline, the lower limit of the hot working temperature of a material is 60% its melting temperature (on … See more • Rolling • Hot spinning • Extrusion • Forging • Drawing See more The advantages are: • Decrease in yield strength, therefore it is easier to work and uses less energy or force • Increase in ductility • Elevated temperatures increase diffusion which can remove or reduce chemical inhomogeneities See more WebCold Working Processes. Abstract: Cold working is the plastic deformation of metals below the recrystallization temperature. In most cases, such cold forming is done at room temperature.
