Alloy

established as a leading role in automotive industry, the use of magnesium in automobile applications is yet limited. Magnesium exhibits a poor formability whereas aluminum has superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic texture \cite{hirsch2013superior}.…

our planet’s mass is metal. They are used as mainly because of their properties; metals are strong, ductile, have high melting points and are excellent conductors of electricity. Other properties of metals are given below: • Can be made stronger by alloys and heat treatment. • Easily machined. • Most of them are heavy. • Susceptible to corrosion. Metals can be divided into two; Ferrous and Non-ferrous. Ferrous metals Ferrous metals are those which contain iron and small amount of other elements.…

strengthened and hardened to an accurately controllable degree. It can be easily casted, corrosion resistant and reproduce fine detail. Moreover, it has high electrical conductivity at high temperatures. To introduce Beryllium into metals, Beryllium alloys of magnesium-aluminum, aluminum, nickel, copper, iron or cobalt are always used (Hornbostel, 1991). According to Harper (2001), Beryllium oxide, with a melting point of 2585 °C and specific gravity of 3.025, is a cubic close-packed and has…

microindentation for Bi57In26Sn17 lead-free alloy data were ensured. 2. The Vickers hardness value for Bi57In26Sn17 lead-free alloy was found affected by the following factors: a). indentation depth b) dwell time. 3. The contact modulus for Bi57In26Sn17 lead-free alloy was dwell-time dependent for small dwell times, and became constant for large dwell times. 6.2 Suggestion It was strongly recommended to prepare the Bi-In-Sn alloy sample with care, since the alloy has a low hardness value…

combination (in liquid state) of one material with other material is used. This mixing of materials in the molten liquid state is termed alloying ,that provides a property that is not similar to the original materials. Bronze is alloy of tin and copper, was the first alloy that is casted by human [11]. Bronze influence the society very much at that time, it was a new milestone in production of material with superior property. Since then, people of material science have been…

Chemistry Task 2 Portfolio Outline and examine some uses of different metals through history, including contemporary uses, as uncombined metals or as alloys. Metal/Metal Alloy Uses Throughout History Copper - Used to make ornaments and domestic utensils in historical times (not as tools as it is a soft metal) - In modern times used in electrical wiring, pipes and plumbing fittings, jewellery, decoration, - This is due to its malleability, ductility and good electrical conductivity. Bronze…

Magnesium wheels are a kind of rims that are used for vehicles. These wheels are generally made of magnesium alloy. These wheels were only used for race cars initially, but these the magnesium wheels are used in a wide range of vehicles. In most cases, the rims of car wheels are made using steel, as it gives great strength to the wheel. However, there are rims which are made using other materials that are as strong as steel. Since the weight of vehicles are reduced by the wheels, the wheels’…

materials that make up these components, as biocompatibility and mechanical properties determine how the implant functions in vivo. The materials used in commercial implants today are Ultra High Molecular Weight Polyethylene, Alumina, and titanium alloys [1]. Ultra-high molecular weight polyethylene (UHMWPE) is a semi- crystalline polymer which is used for the acetabular cup component [3]. UHMWPE has a yield strength of 21 MPa, and ultimate tensile strength of 48 MPa, 350% elongation, and has…

metal alloys such as coins, thermocouples and etc. Copper is essential mostly in some living organisms as the trace dietary mineral. Copper lies below the hydrogen in the electromotive series which it is not soluble in acids with the changes in hydrogen then it will react with oxidizing acids, such as hot and nitric. (The Editors of Encyclopædia Britannica, 2018). Brass, it is also an alloy it was made by a cooper and zinc in these two types of elements brass can be harder and more soften alloy…

bottom of the spine known as the lumbar spine. The stress develops with normal activities such as running, bending, lifting. Jumping, swimming, etc. This research has developed a superlastic adaptive alloy that improves the success rate of scoliosis treatment mostly in children. The material of the alloy is very superlastic and five times more flexible than the currently normal available rods that are used to be implanted in the spine. Materials that are being implanted in the spine must be…
