Heat treatment can be defined as a combination of heating and cooling operations applied to a metal or alloy in its solid state to obtain desired conditions or properties.
Heat treatments can be used to homogenize cast metal alloys to improve their hot workability, to soften metals prior to, and during hot and cold processing operations, or to alter their microstructure in such a way as to achieve the desired mechanical properties.
