Agarwal, Pratik and Sahu, Pallav (2015) Microstructure and Properties Of Az91 Magnesium Alloy. BTech thesis.
Magnesium is the lightest structural metal present on Earths surface. With a density of 1.74g/cc, it gives a high strength to weight ratio. This has made it very useful for many applications like automobile, aeronautical etc. Magnesium has many limitations and because of which it cannot be used directly as a replacement of steel and aluminium. Many alloys of magnesium have been developed to partially or completely overcome the limitations of magnesium without sacrificing other properties. One of the most commonly used commercial alloys is magnesium alloy AZ91, which gives better properties than magnesium. In this project, microstructure and properties of AZ91 in two different casting conditions is compared. The microstructure is observed under the optical microscope. The hardness is measured by Vickers hardness tester. The wear resistance of the sample is compared. The SEM analysis of the wear tested sample is observed. The approximate corrosion rate is also calculated and compared.
