treatment processes. A heat treatment involves rapid heating or cooling of a metal or alloy at extreme temperatures. For decades‚ engineers obtain desirable strength and hardness by austenitizing the steel and then quenching it to form martensitic structure. After fully converting to martensitic‚ steels are tempered to achieve right amount of ductility and hardness. The ability to form martensite on quenching is called hardenability. Both hardness and hardenability solely depends on the composition
