Homonym: quenching (Thirst)
Quenching is a rapid cooling process used primarily in metallurgy to harden metals. This is typically achieved by immersing hot metal, often steel, into a liquid such as water, oil, or brine. The sudden temperature drop alters the metal's microstructure, making it harder and more durable.
In addition to its use in metalworking, quenching can also refer to the process of cooling down hot liquids or gases. For example, in cooking, a chef might quench a hot dish by adding cold ingredients or ice to stop the cooking process and preserve the desired texture and flavor.
