The rapid cooling of a hot metal object, by placing it in a liquid, in order to harden it
Rapid cooling When applicable, the following more specific terms should be used: direct quenching, fog quenching, hot quenching, interrupted quenching, selective quenching, spray quenching, and time quenching
Controlled rapid cooling of a metal from an elevated temperature by contact with a liquid, a gas, or a solid
A processing procedure that describes a variety of processes used to rapidly cool a metal product The process is used to improve specific properties of a metal product
the act of extinguishing; causing to stop burning; "the extinction of the lights"
Rapid cooling, as by immersion in oil or water, of a metal object from the high temperature at which it is shaped. Quenching is usually done to maintain mechanical properties that would be lost with slow cooling. It is commonly applied to steel objects, to which it gives hardness. The quenching media and the type of agitation during quenching are selected to obtain specified physical properties with minimum internal stresses and distortions. Oil is the mildest medium, and salt brine has the strongest quenching effect. In special cases, steel is cooled and held for some time in a molten salt bath, which is kept at a temperature either just above or just below the temperature where martensite begins to form. These two heat treatments, called martempering and austempering, both result in even less distortion of the metal. Copper objects hardened by hammering or other deformation at ordinary temperatures can be restored to malleability by heating and quenching. See also tempering
nibbâna: the going out of a lamp or fire; extinguishing (in general) It is the state of final liberation which the Buddha reached and guided others to The attainment of nibbana is construed differently by Hindus and some Mahayana Buddhists (who use the Sanskrit form "nirvana), and it is better to consult other books on the subject for further information "Quenching" is the most evocative translation of the word, and, I believe, the most accurate
[1] Dipping a heated object into water, oil or other substance, to quickly reduce the temperature Quenching into water gives a more rapid cooling rate than into oil The term also applies to cooling in salt and molten-metal baths or by means of an air blast Applied to steels heated above their upper critical temperature in order to harden them prior to tempering and to other alloys for solution treatment prior to precipitation hardening
Rapid cooling of a work-piece/material from a higher forming/heat treatment temperature to RT [room temperature], to avoid detrimentaldetrimental precipitations, which negatively influence corrosion resistance, strength, etc
Submersing a piece of metal into a fluid bath Primarily used in the processes of cleaning and heat treating processes such as annealing The ideal quenching temperature for annealing varies from metal to metal Some metals are air-cooled before quenching
{f} satisfy a need (esp. thirst); extinguish, put out; cool by immersing in a cold liquid; repress a desire (or urge, etc.); put an end to, destroy; relieve
To quickly place a heated object in cold water This is usually done to either stop the cooking process or to separate the skin of an object from the meat This process is sometimes referred to as "shocking "
Rapid cooling in water to retain compounds in a supersaturated solid solution after the solution heat treatment (usually considered part of the solution heat-treatment process)
electronics: suppress (sparking) when the current is cut off in an inductive circuit, or suppress (an oscillation or discharge) in a component or device
put out, as of fires, flames, or lights; "Too big to be extinguished at once, the forest fires at best could be contained"; "quench the flames"; "snuff out the candles"
cool by plunging into cold water; "quench metal" reduce the degree of (luminescence or phosphorescence) in (excited molecules or a material) by adding a suitable substance satisfy (thirst); "The cold water quenched his thirst" electronics: suppress (sparking) when the current is cut off in an inductive circuit, or suppress (an oscillation or discharge) in a component or device
The rapid cooling of the EDMed surface by the dielectric fluid Partially responsible for metallurgical changes in the recast layer and the heat-affected zone
reduce the degree of (luminescence or phosphorescence) in (excited molecules or a material) by adding a suitable substance satisfy (thirst); "The cold water quenched his thirst"
quenching - loss of superconductivity of the current carrying coil that may occur unexpectedly in a superconducting magnet As the magnet becomes resistive, heat will be released that can result in rapid evaporation of liquid helium in the cryostat
To extinguish; to overwhelm; to make an end of; said of flame and fire, of things burning, and figuratively of sensations and emotions; as, to quench flame; to quench a candle; to quench thirst, love, hate, etc
