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 the deformation of the crystal structure, a process called work hardening. The original properties can be completely restored by full annealing or partially restored by other heat treatment processes such as normalising and process annealing.
