Installation Art
Installation art is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often called public art, land art or art intervention; however, the boundaries between these terms overlap. History Installation art can be either temporary or permanent. Installation artworks have been constructed in exhibition spaces such as museums and galleries, as well as public and private spaces. The genre incorporates a broad range of everyday and natural materials, which are often chosen for their " evocative" qualities, as well as new media such as video, sound, performance, immersive virtual reality and the internet. Many installations are site-specific in that they are designed to exist only in the space for which they were created, appealing to qualities evident in a three-dimensional immersive medium. Artistic collectives such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weathering Steel
Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance after several years' exposure to weather. U.S. Steel (USS) holds the registered trademark on the name COR-TEN. The name COR-TEN refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength. Although USS sold its discrete plate business to International Steel Group (now ArcelorMittal) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. The surface oxidation of weathering steel takes six months, but surface treatmen ...

Richard Serra
Richard Serra (born November 2, 1938) is an American artist known for his large-scale sculptures made for site-specific landscape, urban, and architectural settings. Serra's sculptures are notable for their material quality and exploration of the relationship between the viewer, the work, and the site. Since the mid-1960s, Serra has worked to radicalize and extend the definition of sculpture beginning with his early experiments with rubber, neon, and lead, to his large-scale steel works. Early life and education Serra was born in San Francisco, California to Tony and Gladys Serra – the second of three sons. From a young age, he was encouraged to draw by his mother. The young Serra would carry a small notebook for his sketches and his mother would introduce her son as "Richard the artist." His father worked as a pipe fitter for a shipyard near San Francisco. Serra recounts a memory of a visit to the shipyard to see a boat launch when he was four years old. He watched as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spot Welding
A spot welder Spot welding (or resistance spot welding) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). This permits the welding to occur without excessive heating of the remainder of the sheet. The amount of heat (energy) delivered to the spot is determined by the resistance between the electrodes and the magnitude a ...

Robert Hughes (critic)
Robert Studley Forrest Hughes AO (28 July 19386 August 2012) was an Australian-born art critic, writer, and producer of television documentaries. He was described in 1997 by Robert Boynton of ''The New York Times'' as "the most famous art critic in the world." Hughes earned widespread recognition for his book and television series on modern art, '' The Shock of the New'', and for his longstanding position as art critic with ''TIME'' magazine. He is also known for his best seller ''The Fatal Shore'' (1986), a study of the British convict system in early Australian history. Known for his contentious critiques of art and artists, Hughes was generally conservative in his tastes, although he did not belong to a particular philosophical camp. His writing was noted for its power and elegance. Early life Hughes was born in Sydney, in 1938. His father and paternal grandfather were lawyers.

Rolling Mill
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel Sculptures In Spain
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
