Quenching is the process of cooling a high-carbon steel very quickly after you have heated it, thus " freezing " the steel's molecules in the very hard martensite form, which makes the metal harder.

Quenching and tempering first involve heating the steel to the austenite phase, then quenching it in water or oil.

Quenching is the dominant source of HC at high speeds, and leakage at low speeds.

Fluorophores can also be used to quench the fluorescence of other fluorescent dyes ( see article Quenching ( fluorescence )) or to relay their fluorescence at even longer wavelength ( see article FRET )

Quenching distance plays a vital role in stabilizing the flame in such combustion chambers.

Quenching reduces efficiency and increases knocking, sometimes causing the engine to stall.

Four stars of this constellation ( α, β, γ, δ Lep ) form a quadrilateral and are known as ‘ Arsh al-Jawzā ', " the Throne of Jawzā '" or Kursiyy al-Jawzā ' al-Mu ' akhkhar, " the Hindmost Chair of Jawzā '" and al-Nihāl, " the Camels Quenching Their Thirst " in Arabic.

* April 21 – The Company of Quenching of Fire ( i. e., a fire brigade ) is founded in Edinburgh, Scotland.

Quenching ( to induce martensitic transformation ), followed by tempering will transform some of the brittle martensite into tempered martensite.

Quenching puts an enormous amount of stress on the metal and if cooled unevenly, it can warp the metal, which is how some swords acquire their curvature ; this is called differential hardening.

Quenching refers to all radiationless deexcitation processes in which the excitation is degraded mainly to heat.

The simplest quenching circuit is commonly called Passive Quenching Circuit and composed of a single resistor in series to the SPAD.

The primary work in defense of this theory is DeArteaga's Quenching The Spirit.

Quenching refers to the act of extinguishing the previously established arc within the spark gap.

Quenching metals is a progression ; the first step is soaking the metal, i. e. heating it to the required temperature.

Quenching distance is an important property in the study of combustion.

Quenching hardens the metal so it holds an edge longer but this also makes it very brittle.

Carbon steel, an alloy of iron and carbon, can be very sharp, hold its edge well, and remain easy to sharpen, but is vulnerable to rust and stains.

Carbon and stainless spring steel wire have significant applications for engineered springs for critical automotive or industrial manufactured parts / components.

Carbon steel woks vary widely in price, style, and quality, which is based on ply and forming technique.

Carbon steel is resistant to the most common forms of corrosion, particularly from hydrocarbon impurities at temperatures below 205 ° C, but other corrosive chemicals and environments prevent its use everywhere.

Carbon steel consists of two components: pure iron, in the form of ferrite, and cementite or iron carbide, a compound of iron and carbon.

Carbon steel is steel where the main interstitial alloying constituent is carbon.

Carbon steel is broken down in to four classes based on carbon content:

* Full annealing: Carbon steel is heated to approximately 40 ° C above Ac < sub > 3 </ sub > or Ac < sub > 1 </ sub > for 1 hour ; this assures all the ferrite transforms into austenite ( although cementite might still exist if the carbon content is greater than the eutectoid ).

* Normalizing: Carbon steel is heated to approximately 55 ° C above Ac < sub > 3 </ sub > or Ac < sub > m </ sub > for 1 hour ; this assures the steel completely transforms to austenite.

Carbon composite rotors ( introduced by the Brabham team in 1976 ) are used instead of steel or cast iron because of their superior frictional, thermal, and anti-warping properties, as well as significant weight savings.

Carbon migrates into the steel from the wood.

Carbon flakes or nodules in iron or steel with high carbon content ( high carbon steel, cast iron ) may cause an electrolytic potential and interfere with coating or plating.

Concrete or steel jacketing have been a popular retrofit technique until the advent of composite materials such as Carbon fiber-reinforced polymer ( FRP ).

Carbon ( from " coal ") is the chemical element with symbol C and atomic number 6.

Carbon forms more compounds than any other element, with almost ten million pure organic compounds described to date, which in turn are a tiny fraction of such compounds that are theoretically possible under standard conditions.

Carbon nanotubes ( CNTs ) are allotropes of carbon with a cylindrical nanostructure.

Carbon dating of textiles found with the remains in the cave indicate they are contemporaneous with the period of the Revolt and it is believed that as they were buried with pig bones ( a Roman practice ); this indicates that the remains may belong to Romans who garrisoned Masada after its recapture.

There is much sophisticated engineering and chemistry involved here, with iTi, Pixdro, Asahi Kasei, Merck, BASF, HC Starck, Hitachi Chemical and Frontier Carbon Corporation among the leaders.

Better integration with Mac OS X's application frameworks is provided by APIs layered on top of CGL: AGL for Carbon and NSOpenGL for Cocoa.

Carbon neutral and negative fuels can store and transport renewable energy through existing natural gas pipelines and be used with existing transportation infrastructure, displacing fossil fuels, and reducing greenhouse gases.

In 1971, Schneider was second author on a Science paper with S. I. Rasool titled " Atmospheric Carbon Dioxide and Aerosols: Effects of Large Increases on Global Climate " ( Science 173, 138 – 141 ).

Carbon isotopes of lipids ( n-alkanes ) derived from leaf wax and lignin, and total organic carbon from two sections of lake sediments interbedded with the in eastern North America have shown carbon isotope excursions similar to those found in the mostly marine St. Audrie ’ s Bay section, Somerset, England ; the correlation suggests that the end-Triassic extinction event began at the same time in marine and terrestrial environments, slightly before the oldest basalts in eastern North America but simultaneous with the eruption of the oldest flows in Morocco ( Also suggested by Deenen et al., 2010 ), with both a critical greenhouse and a marine biocalcification crisis.

# Carbon sinks: It was agreed that credit would be granted for broad activities that absorb carbon from the atmosphere or store it, including forest and cropland management, and re-vegetation, with no over-all cap on the amount of credit that a country could claim for sinks activities.
