Cold cracking
Cold cracking, also called hydrogen-induced or delayed cracking, occurs in or beside a steel weld after it cools to near ambient temperature, sometimes days after welding.
Cold extrusion
Cold extrusion, also known as cold forging or cold forming, is a compressive forming process that shapes an unheated metal billet by forcing it through a die.
Cold forging
Cold forging is a metal forming process in which a billet is shaped at room temperature by compressive forces through dies and punches, giving greater dimensional accuracy than hot forging.
Cold forming
Cold forming is a metalworking method that shapes metal plastically at or near room temperature, below its recrystallization temperature, producing strong, precise parts such as bolts, screws, and rivets without heating the workpiece.
Cold gas thruster
A cold gas thruster is a rocket engine that produces thrust by expelling stored pressurized gas through a nozzle without combustion, used mainly for satellite attitude control and small maneuvers.
Cold in-place recycling
Cold in-place recycling (CIR) is a pavement rehabilitation method that mills and reuses existing asphalt in place, without heating, as a base for a new surface.
Cold Lake oil sands operation
The Cold Lake oil sands operation is an in-situ bitumen recovery complex in northeastern Alberta, Canada, owned and operated by Imperial Oil since commercial production began in 1985.
Cold Lake Pipeline
The Cold Lake pipeline is an Inter Pipeline system carrying diluted bitumen from Alberta's Cold Lake oil sands region to terminalling hubs at Edmonton and Hardisty.
Cold launch
Cold launch is a method of launching a missile in which an external source such as compressed air or steam ejects it before the rocket motor ignites.
Cold load pickup
Cold load pickup is the abnormally high demand that appears when electrical loads are re-energized after an outage, reaching several times normal levels and tripping protective relays.
Cold mix asphalt
Cold mix asphalt (CMA) is a bituminous paving mixture of aggregate and liquid binder that is produced, placed, and compacted at ambient air temperature, without heating.
Cold plate (refrigeration)
A cold plate, also called a eutectic plate or hold-over plate, is a sealed container of phase-change solution frozen in advance to refrigerate without a running compressor.
Cold rolling
Cold rolling is a metal forming process that reduces the thickness of metal below its recrystallization temperature, work-hardening it and improving surface finish in sheet, strip, and foil.
Cold shock response
Cold shock response, also known as cold water shock or hydrocution, is a life-threatening reflex of gasping, hyperventilation, and heart strain triggered by sudden immersion in water below 15°C (59°F).
Cold sintering process
The cold sintering process (CSP) is a ceramic processing technique that densifies inorganic powders below about 300 °C using a transient liquid phase and uniaxial pressure.
Cold spray
Cold spray is a solid-state coating and additive manufacturing process in which supersonic gas jets accelerate metal powder particles that bond through plastic deformation alone, without melting.
Cold start (recommender systems)
Cold start is the problem a recommender system faces when it must recommend for a new user or item that has no interaction history, so collaborative filtering has nothing to learn from.
Cold War propellant development
Cold War propellant development was the maturation of cryogenic liquids, storable hypergolics, and large solid motors, driven by the 1950s and 1960s ballistic missile race.
Cold welding
Cold welding, also known as contact welding or cold pressure welding, is a solid-state joining process that bonds metals under pressure without melting, used for copper and aluminum wire.
Cold-chain AS/RS
A cold-chain AS/RS is an automated storage and retrieval system inside refrigerated, chilled, and frozen warehouses, moving pallets of food and pharmaceuticals without sustained human presence in the cold zone.
Colditz Castle
Colditz Castle (Schloss Colditz) is a castle in Saxony, Germany, first recorded in 1046 and best known as the officers' POW camp Oflag IV C in the Second World War, whose escape attempts made it famous.
Coleco
Coleco, founded in 1932 as the Connecticut Leather Company, was an American toy and electronics company known for the ColecoVision console and Cabbage Patch Kids, entering bankruptcy in 1988.
Coleco Adam
The Coleco Adam is a complete home computer system released in 1983 by Coleco Industries, sold bundled with a printer and tape drive before its 1985 discontinuation.
Colegio de Ingenieros de Caminos, Canales y Puertos

Coleman Company
The Coleman Company is an American manufacturer of camping and outdoor equipment such as lanterns, stoves, coolers, and tents, founded in 1900 and owned by Newell Brands since 2016.
Coleman Dupont Donaldson
Coleman Dupont Donaldson (1922–2009) was an American aeronautical engineer known for second-order closure modeling of turbulent flows, transonic wind-tunnel research, and the national study of the aircraft wake vortex hazard.
Coleman Mine
Coleman Mine is an underground nickel-copper mine in Levack Township, about 50 km north of Sudbury, Ontario, one of five underground mines in Vale's Sudbury operations, producing since 1970.
Colgan Air Flight 3407
Colgan Air Flight 3407 was a commuter flight from Newark to Buffalo that crashed in Clarence Center, New York, on February 12, 2009, killing 50.
Colgate (toothpaste)
