Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400 Brinell measurement. Magnesium alloys have a low density but stand greater column loading per unit weight and have a higher specific modulus. Magnesium alloys harden rapidly with any type of cold work, therefore they cannot extensively be formed without

Cast Iron is processed to remove impurities or slag and is turned into a steel alloy. Therefore steel is an alloy and Iron is an element. Steel is also called as an alloy of iron, with the content of carbon controlled. 4% of carbon in Iron makes it Cast Iron and when the carbon content is less than 2%, the product is steel. Cast Iron is made from pig iron, which is the by-product of smelting of iron from an iron-foundry.
Mild steel, which is also known as plain carbon steel, approximately contains 0.05-0.15% of carbon. This makes it malleable and ductile. Mild steel has a relatively low tensile strength, it is cheap and the formation is easy. The surface tension of mild steel can be increased by carburizing. Mild steel is used when large quantities of steel are required. The Density of mild steel is approximately 7.85g/cm^3 and the young’s modulus is 210

You can choose different percentage of chemical composition and control, and adapt it to the various requirements of the product. Mild steel has good weld-ability and machine-ability. The weight of Mild steel is much less when compared to Iron. Fig (10) Picture source: https://www.castrads.com/workspace/images/spares-accessories/1.25in-0.5in-cast-iron-reducing-bush.jpg
Cast Iron is nothing but a group of iron-carbon alloys which has carbon content greater than 2%. The constituents of the alloy affect the colour when fractured. Carbon and Silicon are the main alloying element, with amounts ranging from 2.1-4wt% and 1-3wt% respectively. Cast Iron is usually brittle except malleable cast irons. It has a low melting when compared to pure iron (572K lesser than the melting point of pure iron). The melting point ranges from 1422K to 1722k. Cast iron has good fluidity, cast-ability, good machine-ability, excellent resistance to deformation. Cast Iron have become a good engineering material with applications in machines, automotive industry parts such as cylinder heads, cylinder blocks, and gearbox cases. It has resistance to destruction and weakening by oxidation

    However one disadvantage of the using steel is because it consists of iron atoms. Iron is reactive to both water and oxygen, and when these elements react together it forms –iron oxide (rust). Rust can reduce the effectiveness and efficiency of the material. So you should be very careful whilst handling steel in construction.…

    Welding can be very fun and empowering. Watching the sparks fly from the metals, and seeing the world’s strongest metals be made into what a welder wants for it to become. Welding requires hard work and a considerable amount of practice. It requires hard work, dedication, and concentration. If one welder does not pay attention to their work it could result in a considerable amount of damage to yourself and even others.…

    Jessica Tan Mr. Chlodnicki Comparative Cultures Period 1 7 October 2014 Essay 1: Why were Europeans able to conquer large parts of the world during the Age of Imperialism? Europeans were able to take over most of the Americas, some of the African continent, and parts of Asia, during a time period known as the Age of Imperialism. Prior to the Age of Imperialism, Europeans had not been able to conquer much of the world, since they did not have the military technology or economical wealth to do so. Due to its development of new military strategies, Europe was able to build colonies across the globe during the Age of Imperialism, with the aid of agricultural advancements. With the development in weaponry, military strategies that were newer…

    Have you ever wondered how things like cars, buildings, and bridges are built? Welding is a widely used way to join structural and ornamental iron and steel. Many of the things we use in our daily lives are welded, like buildings, bridges and vehicles. Welding is the process of joining two metals with electricity and heat to make one piece of metal. The two main types of welding are arc welding and brazing.…

    EXPANSION AND IMPORTANCE OF THE BRITISH STEEL INDUSTRY AND TRADE DURING THE INDUSTRIAL REVOLUTION Introduction In the paper it will be explained the importance of the steel as a commodity throughout the latter part of the 19th century during the Industrial Revolution in Britain, as well as the impact of the production and its trade, exposing political, economic and social aspects that were directly affected by the technological development of Britain in matter of steel. The steel, according to the Oxford Dictionaries is a hard “alloy of iron with carbon and usually other elements, used as a structural and fabricating material” (2015), and it was usually used for industrial purposes, as well for constructing and railroads. (Gordon, 1910) It…

    Introduction The process of welding developed from Blacksmithing. In the 19th century, Edmund Davy discovered an impacting thing for the welding industry, which was the way we know welding is done now, with flames. To me the way that was used back then just seems like a waste of time, but as time flies by many things change by so much. There is many different types of welding method.…

Composite materials are materials in which a homogenous matrix is reinforced by a stronger and stiffer constituent that is usually fibrous but may have a particulate or other shape (web.mit.edu). They are produced when two or more materials or phases are used together to give a combination of properties that cannot be attained otherwise. For example steel reinforced concrete, plywood and fibre glass. 1.2…

    The calcium phosphate without the magnesium produces higher crystalline and crystal size in composition. While the increase in the magnesium content will make the XRD peaks become significantly broader. This is due to decreased in crystalline size with the increase in the lattice disorder (Hanifi and Fathi, 2010).

    HARDNESS Hardness of a material is most commonly defined as the measure of its resistance to penentration by an indenter. Hardness is also measure of strength and often has the units of stress .The indenter is often fabricated from a hard material such as diamond or hardened steel. The tips of the indenters may be conical,pyramidal,or spherical in shape. The indenter tips may also be relatively small(nano-or micro-indenters) or very large(macroindenters).Since indentation tests are relatively easy to perform(macroindentations require only limited specimen preparation),they are often used to obtain quick estimates of strength.…
