Abstract
In the world of advance development, rapid growth for any nation, country or individual is a must thing to have. There are several studies and researches that have put forward to us, not only revolutionized the human society but also helped us to live a better life in a better way. This study focusses on a similar track to analyze the characteristics of magnesium alloys; known for its high weight to strength ratio, so that it could replace; at time; extensively used materials i.e. steel and aluminum. The magnesium alloy has several advantages over steel and aluminum i.e. due to its low density, its weight is quite low, which is the reason that it is extensively used in aerospace and outer space application. Studies suggests that Low weight allows system to consume lesser fuel as compare to the normal ones. Along with it, inspite of having lesser density it doesn't compromises its mechanical strength and provide high weight to strength ratio; which makes it more suitable for structural and automotive applications. However, inspite of having such tremendous advantages, there are some drawbacks which leads to its minimum usage as compare to both the materials. Magnesium alloys have low ductility, however, it can be enhanced to certain level by several methods to make it cope with real world industrial, commercial and residential applications. This study focusses on analyzing the mechanical and structural characteristics of two grades of magnesium alloy i.e. AZ31 and AZ61. The conclusion has been made by carrying out different mechanical tests i.e. tensile testing, Brinell hardness testing, torsion testing and cupping testing. After conducting these tests this was concluded that AZ31 and AZ61 are a good replacement for aluminium as it has a poison's ration of 0.4 and 0.24 respectively.
