The plastic deformation of metal at such a The temperature of the forging stock just prior to forging. and The rate at which metal is deformed. that recrystallization takes place simultaneously with the deformation, thus avoiding any An increase in hardness and strength caused by plastic deformation at temperatures below the recrystallization range. Also known as work hardening.. Also referred to as Same 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 Permanent 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.
