Hot working

The plastic deformation of metal at such a temperatureThe temperature of the forging stock just prior to forging. and strain rateThe rate at which metal is deformed. that recrystallization takes place simultaneously with the deformation, thus avoiding any strain hardeningAn increase in hardness and strength caused by plastic deformation at temperatures below the recrystallization range. Also known as work hardening.. Also referred to as hot forgingSame as hot working—plastically deforming an alloy at a temperature above its recrystallization point, i.e, high enough to avoid strain hardening. and hot forming. Contrast with cold workingPermanent plastic deformation of a metal at a temperature below its recrystallization point—low enough to produce strain hardening. Usually, but not necessarily, conducted at room temperature. Also referred to as cold forming or cold forging. Contrast with hot working.... More.
