Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• Common heat treatment processes include annealing, tempering, quenching, and case hardening.
