• Metal heat treatment
  • Metal heat treatment is defined as an operation involving the heating and cooling of a metal or an alloy in the solid-state to obtain certain desirable properties without change composition. The process of heat treatment is carried out to change the grain size, to modify the structure of the material, and to relieve the stresses set up the material after hot or cold working.

    Heat treatment consists of heating the metal near or above its critical temperature, held for a particular time at that finally cooling the metal in some medium which may be air, water, brine, or molten salts. The heat treatment process includes annealing, case hardening, tempering, normalizing and quenching, nitriding, cyaniding, etc.

    Types of Heat Treatment Processes
    Following are the different types of heat treatment processes:

    Annealing
    Normalizing
    hardening
    Tempering
    Nitriding
    Cyaniding
    Induction Hardening
    Flame Hardening
