Mechanically forming material at about room temperature.
Cold working processes include rolling, drawing, spinning, hammering, etc. As the amount of cold work increases the material gets harder owing to theĀ deformationĀ of theĀ crystal structure, a process calledĀ work hardening. The original properties can be completely restored byĀ full annealingĀ or partially restored by other heat treatment processes such asĀ normalisingĀ andĀ process annealing.
