This process is known as tempering. (See Processing Metals Activity). It results in many small Fe 3 C precipitates in the steel, which block disloion motion which thereby provide the strengthening. Cold Working: Because plastic deformation results from the movement of disloions, metals can be strengthened by preventing this motion.
