The rapid cooling of a metal by immersing it in a bath of liquid in order to improve its properties. (Course Material/PenetrantTest/Principles/commonuses.htm)
A closely controlled rapid cooling of metal from some type of high temperature operation such as heat treating or extruding. The cooling medium is usually water and the purpose is to chill the metal quickly and lock the alloying elements into the dispersed positions imparted to them by the high temperature operation.
A treatment consisting of heating uniformly to a predetermined temperature and cooling rapidly in air or liquid medium to produce a desired crystalline structure.
Controlled rapid cooling of a metal from an elevated temperature by contact with a liquid, a gas, or a solid.
Cooling rapidly by immersion in oil, water, etc.
Abrupt cooling of a burning substance in order to arrest phase transformations and chemical reactions in a sample
Rapid cooling of a heated metal, generally by immersion in liquids, to increase strength and hardness. Quenching is always followed by a temper to increase ductility.
A process of rapid cooling from an elevated temperature by contact with low temperature liquids, gases or solids.
Rapidly cooling a metal from a high temperature.
The rapid cooling of a heated object.
Rapid cooling. When applicable, the following more specific terms should be used: brine quenching, caustic quenching, cold die quenching, forced-air quenching, intense quenching, oil quenching, press quenching, spray quenching, direct quenching, fog quenching, hot quenching, interrupted quenching, and water quenching.
Rapid cooling of metals (often steels) from a suitable elevated temperature. This generally is accomplished by immersion in water, oil, polymer solution, or salt, although forced air is sometimes used.
An accelerated cooling method used for increasing the hardness and strength of carbon and alloy steels, which is normally followed by a tempering cycle. Quenching normally implies immersion in a liquid such as water or oil. In the solution treatment of austenitic stainless steels and nickel based alloys a water quench is used to keep carbides in solution. The quench cycle is normally complete when the item being quenched cools to around 212 F (100 C).
Cooling from high temperature, usually at a fast rate.
Rapidly cooling metal in oil or water. Used in certain kinds of heat treatment to increase or lessen hardness. Back to the Top
1. Cooling of steel in cold water to increase its hardness. 2. Rapid cooling of metal in a heat treating process.
Rapid cooling from a high temperature by immersion in a liquid bath of oil or water. Molten salts may also be used.
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 cooling of fiber filaments after extrusion by carefully controlled airflow. (See CROSSFLOW QUENCH INFLOW QUENCH and OUTFLOW QUENCH.)
Cooling by immersion in some medium, which may be any liquid or gas, or even a solid in suitable form, to absorb heat rapidly from the article to be quenched.
the process of cooling steel suddenly by immersion, usually in water or oil.
Rapid cooling from an elevated temperature, e.g., severe cooling of the reaction system in a short time (almost instantaneously), “freezes” the status of a reaction and prevents further decomposition.
A technique used for stopping one process with another. In metal or glass formation, crystal formation during cooling can be stopped by rapid quenching with air or water. Radian A measurement of angle. There are 2 r radians in a full circle of 360 angular degrees. Radiance The total intensity of thermal energy (radiant flux) which can be observed from a surface. It is scaled by unit of solid angle of view and by unit of area from the surface. The flux includes all forms of radiation emission, reflection and transmission.
Dipping a heated object into water, oil or other substance, to quickly reduce the temperature.
Cooling metal rapidly by using water, cold air or oil.
