Small staysail located between the foremast and mainmast.

Aging induced by rapid cooling after solution heat treatment.

Fracture of a metal during quenching from elevated temperature. Most frequently observed in hardened carbon steel, alloy steel, or tool steel parts of high hardness and low toughness. Cracks often emanate from fillets, holes, corners, or other stress rais ...

(1) Hardening suitable a = b alloys (most often certain copper or titanium alloys) by solution treating and quenching to develop a martensite-like structure. (2) In ferrous alloys, hardening by austenitizing and then cooling at a rate such that a substant ...

Embrittlement of low-carbon steels resulting from precipitation of solute carbon at existing dislocations and from precipitation hardening of the steel caused by differences in the solid solubility of carbon in ferrite at different temperatures. Quench-ag ...

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.

A coupling device which consists of a spring loaded shutoff valve and a positive locking mechanism. It is used to connect tools, hoses and other accessories. Also known as Quick Disconnect.

A navigational aid with a light that flashes about once per second.

A wedge-shaped piece of timber used to secure barrels against movement.

The quantity of goods that may be imported without restriction during a set period of time.
