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.
The properties of heat treated steel are significantly affected by the thickness of the section. Hardening consist of heating the steel through and just above its critical range to obtain the condition of solid solution and quenching with sufficient rapidity to retain this condition.
