Quenching is a heat treatment process that involves heating steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hyper-eutectoid steel), preserving the heat for a period of time to allow for complete or partial austenitization of the steel, then cooling it off rapidly at a rate above the critical cooling rate, to a temperature below Ms for martensite (or bainite) transformation (or isothermal near Ms). From time to time, quenching also entails solution treatment of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass; or heat treatment involving rapid cooling processes.
