2.Traditionally metals have been classified as ferrous and non ferrous.The ferrous category refers to base metals of iron, while the non ferrous metals are iron free. Ferrous alloys are used in quantities which exceed all other metals combined. At the present time there are available for use in excess of 45,000different metallic alloys. Although the steels and cast irons make up the largest use on a weight basis, the number of different nonferrous alloys exceed the number of ferrous alloys.

5.Corrosion resistance must also be taken into account. This applies whether the exposure is to the natural atmosphere, to a more aggressive atmosphere, or to physical contact with a corrosion.

1.Metals have been widely used for thousands of years, commencing with the Bronze Age which took place approximately 3000 to 100 years BC. The Iron Age, which we are experiencing today, presumably replaced the Bronze Age. Although we still use considerable amounts of bronze, our steel use is many times greater.

          3.Although the steels and cast irons make up the largest use on a weight basis, the number of different nonferrous alloys exceed the number of ferrous alloys. The primary nonferrous alloys consist of either aluminum, copper, nickel, magnesium, titanium, or zinc .The engineer or designer is faced with the problem of material selection for his or her project. A decision must be based on information that will permit selection of a material that will possess the necessary physical, mechanical, and corrosion resistance properties in addition to cost considerations.

          6.Cost is not only the raw material cost, but rather the finished manufactured cost in conjunction with estimated life of the finished product. The raw material with the lowest cost is not necessarily the most economical choice. Part of the selection process necessitates the examination of the physical and mechanical properties. Physical behavior deals with electrical, optical,  magnetic, and thermal properties. Mechanical behavior deals with the reaction of the body to a load or force.

                The distinction between hot working and cold working does not depends solely on the temperature, but rather on the processing temperature with respect to the material recrystallization temperature. When the processing temperature of the mechanical deformation of steel is above the recrystallization temperature, the process is termed as hot working; otherwise, it is cold working.For hot working processes, large deformation can be successively repeated, as the metal remains soft and ductile. The hardness of the material cannot be controlled after hot rolling and it is a function of chemical composition and the rate of cooling after rolling. The hardness is generally lower than that of cold rolling and the required deformation energy is lesser as well. However most metal will experience some surface oxidation resulting in material loss and poor final surface finish.Cold working processes allow desirable metal qualities that cannot be obtained by hot working, such as eliminating errors attending shrinkage.

 

Вариант 2.

 

Translate the text

 

As such, a much more compact and higher dimensional accuracy metal can be obtained with cold working. Furthermore, the final products have a smoother surface (better surface finish) than those of hot working and the strength, hardness as well as the elastic limit are increased. However, the ductility of the metal decreases due to strain hardening thus making the metal more brittle. As such, the metal must be heated from time to time (annealed) during the rolling operation to remove the undesirable effects of cold working and to increase the workability of the metal. The advantages of endless rolling over conventional rolling include improvements in the uniformity of the metal qualities such as dimension, profile and microstructure throughout the whole length as the joined metal sheets can be finish-rolled at a constant speed over the whole length without any interruption, thus improving productivity. Yield is also improved as the crops are not cut. Furthermore with endless rolling process, hot strip with thickness under 0.8mm can be produced. In cold rolling, the metal piece is not heated immediately prior to rolling but the temperature of the work piece will rise due to the frictional effects of rolling. Steels that are cold rolled become work hardened and annealing is required in order to obtain the desired hardness. The difference between hot rolled and cold rolled steels is the mechanical and chemical properties of the end products.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is mostly used as a pure metal, but when a higher hardness is required it is combined with other elements to make an alloy (5% of total use) such as brass and bronze. A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics.

Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring with the major exception being overhead electric power transmission where aluminium is often preferred. Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Electrical wiring is the most important market for the copper industry. This includes building wire, communications cable, power distribution cable, appliance wire, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, solderHYPERLINK "http://en.wikipedia.org/wiki/Solder" HYPERLINK "http://en.wikipedia.org/wiki/Solder"ability, and ease of installation.

Integrated circuits and printed circuit boards increasingly feature copper in place of aluminium because of its superior electrical conductivity heat sinks and heat exchangers use copper as a result of its superior heat dissipation capacity to aluminium. Electromagnets, vacuum tubes, cathode ray tubes, and magnetrons in microwave ovens use copper, as do wave guides for microwave radiation.

Copper’s greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.

Copper has been used since ancient times as a durable, corrosion resistant, and weatherproof architectural material. Roofs, flashings, rain gutters, downspouts, domes, spires, vaults, and doors have been made from copper for hundreds or thousands of years. Copper’s architectural use has been expanded in modern times to include interior and exterior wall cladding, building expansion joints, radio frequency shielding, and antimicrobial indoor products, such as attractive handrails, bathroom fixtures, and counter tops. Some of copper’s other important benefits as an architectural material include its low thermal movement, light weight, lightning protection, and its recyclability.

Uranium is a silvery-white metallic chemical element in the actinide series of the periodic table, with symbol U. Uranium is weakly radioactive. Many contemporary uses of uranium exploit its unique nuclear properties. Research by Enrico Fermi and others starting in 1934 led to its use as a fuel in the nuclear power industry, the first nuclear weapon used in war. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium-239. The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is an ongoing concern for public health and safety. The major application of uranium in the military sector is in high-density penetrators. This ammunition consists of depleted uranium (DU) alloyed with 1–2% other elements. At high impact speed, the density, hardness  of the projectile enable destruction of heavily armored targets. Tank armor and other removable vehicle armor are also hardened with depleted uranium plates. The use of depleted uranium became politically and environmentally contentious after the use of depleted uranium munitions by the US, UK and other countries during wars in the Persian Gulf and the Balkans raised questions of uranium compounds left in the soil. During the later stages of World War II, the entire Cold War, and to a lesser extent afterwards, uranium-235 has been used as the fissile explosive material to produce nuclear weapons. The mushroom cloud over Hiroshima after the dropping of the uranium-based atomic bomb nicknamed 'Little Boy'.

Reading the text

Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device (codenamed "Little Boy") whose fissile material was highly enriched uranium, and a plutonium-based device whose plutonium was derived from uranium-238. The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August 1945. Exploding with a yield equivalent to 12,500 tons of TNT, the blast and thermal wave of the bomb destroyed nearly 50,000 buildings and killed approximately 75,000 people (see Atomic bombings of Hiroshima and Nagasaki).[23] Initially it was believed that uranium was relatively rare, and that nuclear proliferation could be avoided by simply buying up all known uranium stocks, but within a decade large deposits of it were discovered in many places around the world. The most visible civilian use of uranium is as the thermal power source used in nuclear power plants.

The main use of uranium in the Commercial nuclear power plants use fuel civilian sector is to fuel nuclear power plants. That is typically enriched to around 3% uranium-235. The CANDU and Magnox designs are the only commercial reactors capable of using enriched uranium fuel. Fuel used for United States Navy reactors is typically highly enriched in uranium-235. The world's first commercial scale nuclear power station, Obninsk in the Soviet Union, began generation with its reactor AM-1 on 27 June 1954. Other early nuclear power plants were Calder Hall in England which began generation on 17 October 1956 and the Atomic Power Station in Pennsylvania which began on 26 May 1958. Nuclear power was used for the first time for propulsion by a submarine, the USS HYPERLINK "http://en.wikipedia.org/wiki/USS_Nautilus_(SSN-571)"Nautilus, in 1954.

Read the text.

People have been recycling metals for hundreds of years. Today, re-using metal waste or scrap provides work for many people, especially in developing countries. Three kinds of metals are recycled. They are ferrous metals, non-ferrous metals and precious metals.

Ferrous metals contain iron. They are low in cost and recycled in huge amounts. Metallic iron called pig iron is produced when iron is heated in a hot industrial stove. This kind of stove is called a blast furnace. Pig iron also contains another element, carbon. Pig iron is useful because it can be formed into solid, heavy objects or objects with unusual shapes.

Another kind of iron is steel, which is iron without the carbon. Making steel is simply removing the carbon by burning it away. This makes the steel stronger and easier to cut than iron. Both pig iron and steel waste or scrap are useful because they can be melted to make new products.

In countries where there is a shortage of steel scrap, old tin cans are sometimes used and melted. Tin cans are mostly steel. If the scrap is heated before the temperature gets to the melting point, the blast furnace can be more simply designed and less costly. These simpler furnaces are called foundries. Products are made in foundries all over the world, but especially in Asia.

Non-ferrous metals include copper and aluminum. Copper is the perfect material for recycling. It is valuable, easy to identify and easy to clean. People who operate foundries around the world buy copper wire and cable to recycle.

Aluminum is another very popular non-ferrous scrap metal. It is cheap to produce and very easy to work with. In developing countries, small foundries produce aluminum bars, sheets and wire.

Precious metals like silver also are recycled. Silver can be found in pictures made with old cameras. And it can be found in X-rays after they have been developed. X-ray film is very valuable for recycling silver, because both sides of the film are usually developed.
