Background

In the field of quenching technology, for example, quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), held for a period of time to austenitize all or part of the steel, and then rapidly cooled to a temperature below Ms (or isothermal near Ms) at a cooling rate greater than the critical cooling rate to perform martensite (or bainite) transformation. The solution treatment or heat treatment process with a rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass, etc. is also generally called quenching.
