  • Processing Metals - University Of Illinois

    When this is done at or near room temperature, the process is known as cold-working. When cold-worked metals are annealed (heated gently), new grains form from the cold worked structure and grow until they replace it with new, soft crystals. Steels (alloys of iron with up to 1% carbon) can also be hardened by heating and quenching.
