Plastic deformation at temperatures and rates where substantial increases can occur in the strength and hardness of the metal. Visible structural changes, e.g. modifications in grain shape, are characteristic of cold-work. The treatment usually consists of rolling, hammering or drawing at room temperatures when the hardness and tensile strength are increased with the amount of cold-work, but the ductility and impact strength are reduced.
