[0002] Quenching is a kind of heat treatment process. Steel quenching is to heat the steel to the critical temperature of hypoeutectoid steel or hypereutectoid steel above the temperature, keep warm for a period of time, make it all or part of austenitizing, and then cool to Ms below with a cooling rate greater than the critical cooling rate to carry out martensitic transformation. The solid solution treatment or heat treatment process with rapid cooling process of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials is also called quenching.
