[0002] Quenching is one of the metal heat treatment processes, mainly used for enhancing the hardness of steel and other alloys. Its basic process includes heating the material to a specific temperature, maintaining it for a period of time to ensure complete austenitization, and then rapidly cooling it, usually through oil, water or air medium. Rapid cooling inhibits the transformation of high-temperature phases to low-temperature phases, resulting in the formation of hard and brittle martensite structure. Quenching can significantly improve the hardness and strength of metal materials, but at the same time, it can also make them brittle and may generate large internal stress, so it is often combined with tempering to improve the toughness of the material.
