Citadel Of Huy
The Fort of Huy (french: Fort de Huy) or the Citadel of Huy (french: Citadelle de Huy), known locally as The Castle ( wa, Li Tchestia), is a fortress located in the Wallonia, Walloon city of Huy in the Liège (province), province of Liège, Belgium. The fort occupies a high position in the town, overlooking the strategic Meuse river. The site of the citadel has been fortified since the ninth century, and various structures have been built on the site. The current fort dates to in 1818 during United Kingdom of the Netherlands, the period of Dutch rule in Belgium and took five years to build. The Citadel was frequently used to house political prisoners. In the 19th century, members of the revolutionary Belgian Legion were imprisoned after their failed invasion of Belgium at Risquons-Tout in 1848. During the German occupation of Belgium during World War II, German occupation of Belgium in World War II, six thousand Belgian political prisoners, including the Communist Julien Lahaut, w ...

Cockerill-Sambre
Cockerill-Sambre was a group of Belgian steel manufacturers headquartered in Seraing, on the river Meuse, and in Charleroi, on the river Sambre. The Cockerill-Sambre group was formed in 1981 by the merger of two Belgian steel groups – SA Cockerill-Ougrée based at Seraing in the province of Liège, and Hainaut-Sambre based at Charleroi in the province of Hainaut – both being the result of post-World War II consolidations of the Belgian steel industry. The company inherited a steel industry with significant debts and production overcapacity based on blast furnace production rather than electric furnace recycling, with numerous factory sites in constrained city locations, and adversely affected by competition in the export market from new steel-producing countries (such as South Korea and Brasil). The need to streamline was complicated by regional dependence on employment in the steel industry. It was merged into Usinor in 1999, and after 2002 was part of the Arcelor group. A ...

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Brittleness
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound. When used in materials science, it is generally applied to materials that fail when there is little or no plastic deformation before failure. One proof is to match the broken halves, which should fit exactly since no plastic deformation has occurred. Brittleness in different materials Polymers Mechanical characteristics of polymers can be sensitive to temperature changes near room temperatures. For example, poly(methyl methacrylate) is extremely brittle at temperature 4˚C, but experiences increased ductility with increased temperature. Amorphous polymers are polymers that can behave differently at different temperatures. They may behave like a glass at low temperatures (the glassy ...

Steel
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Damage
Hydrogen damage is the generic name given to a large number of metal degradation processes due to interaction with hydrogen atoms. Note that molecular gaseous hydrogen does not have the same effect as atoms or ions released into solid solution in the metal. Creation of internal defects Carbon steels exposed to hydrogen at high temperatures experience high temperature hydrogen attack which leads to internal decarburization and weakening. Blistering Atomic hydrogen diffusing through metals may collect at internal defects like inclusions and laminations and form molecular hydrogen. High pressures may be built up at such locations due to continued absorption of hydrogen leading to blister formation, growth and eventual bursting of the blister. Such hydrogen induced blister cracking has been observed in steels, aluminium alloys, titanium alloys and nuclear structural materials. Metals with low hydrogen solubility (such as tungsten) are more susceptible to blister formation. While i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
