Magnesium Alloy:
Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html
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 …show more content…
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 …show more content…
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
