I pass this heat treatment definition along until I'm corrected or find a more succinct, better one. Heat treatment is the controlled heating and cooling of a metal in order to change its properties. Forging is controlled heating and cooling but is not considered a heat treatment by metallurgists, probably because of the plastic deformation involved.
After steel has been tempered, it can be easily shaped, cut and filed, which is important in the manufacturing process. Outside of manufacturing, heat treatment of steel is carried out in metal workshops for students. When metal is tempered, it turns different colors based on the amount of heat to which it is exposed.
