In materials science, quenching, a type of heat treating, is the rapid cooling of a workpiece to obtain certain material properties. It prevents low-temperature processes, such as phase transformations, from occurring by only providing a narrow window of time in which the reaction is both thermodynamically favorable and kinetically accessible. For instance, it can reduce crystallinity and thereby increase the hardness of both alloys and plastics (produced through polymerization).
In metallurgy, it is most commonly used to harden steel by introducing martensite, in which case the steel must be rapidly cooled through its eutectoid point, the temperature at which austenite becomes unstable. In steel alloyed with metals such as nickel and manganese, the eutectoid temperature becomes much lower, but the kinetic barriers to phase transformation remain the same. This allows quenching to start at a lower temperature, making the process much easier. High speed steel also has added tungsten, which serves to raise kinetic barriers and give the illusion that the material has been cooled more rapidly than it really has. Even cooling such alloys slowly in air has most of the desired effects of quenching.
Quench USA Inc is a water technology company that rents and services filtered water coolers. According to the site, over half of the Fortune 500 are customers. Zenith International lists Quench as a leading distributor in the point-of-use (POU) market along with Macke Water Systems and Nestle Waters. Quench is an independent operating company of AquaVenture Holdings™. Quench is headquartered in King of Prussia, Pennsylvania. Quench was named an Online Marketing Success Story in Google's 2011 Economic Impact Report. In 2008, Quench was named a top 25 most successful startup by Businessweek.
Filtered water systems are plumbed into a building's water supply and purified at the last possible point before consumption. Filter water coolers and ice dispensers typically use carbon filtration, UV water disinfection and/or reverse osmosis to purify drinking water.
In March 2012, Quench purchased Aqua Perfect of Arizona LLC. In July of 2105 Quench acquired Region-X LLC a Massachuetts company that provides services related to high purity water systems
Quench released in the UK on 17 October 1998 is The Beautiful South's sixth original album. Including the compilation Carry On Up The Charts it was the band's third album in a row to reach the top of the charts.
The cover depicts a boxer by Scottish painter Peter Howson. Commissioned for the album, the original painting can be seen in the Ferens Art Gallery, Hull. After the band cropped the image and used it in merchandise and promotional material, Howson took legal action against the band, receiving around £30,000 in damages. Whilst the first two singles from the album also have artwork by Howson, "How Long's a Tear Take to Dry?" and "The Table" do not.

Norman Howell (born May 11, 1973, Hartford, Connecticut), better known as Notch, is an R&B, reggae, dancehall and reggaeton artist. He was the former lead vocalist and one of the creative force behind the hip hop-reggae act, Born Jamericans.
He has been featured on hit albums such as Mas Flow 2, Mas Flow 2.5, Chosen Few II: El Documental, Barrio Fino, and The Cosmic Game. His first solo album, Raised by the People, was released in May 2007.
Notch's mother is African American of Native American, Portuguese, and Puerto Rican descent, his father was born in Jamaica and is of Afro-Cuban and French descent. His parents separated while still an infant. He spent his early years with his mother living in Hartford, Connecticut. He grew up in a multicultural neighborhood. Notch learned how to speak Spanish because most of his friends at that time were of Hispanic descent. He went to go live with his father in Washington D.C. when he was nine years old. Notch also spent a short time in Bermuda before moving back to Washington D.C. where he lived until his early twenties.
Markus Alexej Persson (born 1 June 1979), also known as Notch or xNotch, is a Swedish video game programmer and designer who founded the video game company Mojang alongside Carl Manneh and Jakob Porser in late 2010.
Persson's principal venture for founding Mojang was Minecraft, a first-person sandbox video game that has gained popularity and support since its tech demo in 2009. Since the release of Minecraft, Persson has gained significant notability within the video game industry, having won multiple awards and establishing relations with the industry's figureheads. Persson retained his position as the lead designer of Minecraft until the game's official launch in 2011, after which he transferred creative authority to Jens Bergensten. In November 2014, he left Mojang after its acquisition by Microsoft.
Persson was born in Stockholm,Sweden, to a Finnish mother and a Swedish father on 1 June 1979. He lived in Edsbyn for the first seven years of his life before his family moved back to Stockholm. He began programming on his father's Commodore 128 home computer at the age of seven. Having experimented with various type-in programs he produced his first game at the age of eight, a text-based adventure game. Professionally he had worked as a game developer for King.com for over four years, until 2009. Afterwards he worked as a programmer for Jalbum. He is also one of the founders of Wurm Online, although he no longer works on this game. Outside of work, he has made seven games for competitions for the Java 4K Game Programming Contest such as "Left 4K Dead" and "MEGA4kMAN". He has also entered the Ludum Dare competition. He is the central figure of a documentary by 2 Player Productions about the rise of Minecraft and Mojang called Minecraft: The Story of Mojang.
