Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
Annealing, normalizing, hardening/quenching and tempering are the most important heat treatments often used to modify the. microstructure and desired mechanical properties in steel [6]. Heat treatment process leads to change in phase. microstructural and crystallographic changes in material [3].
