Evaluation of microstructure and mechanical properties of magnesium alloys by stir casting process

Magnesium alloys are light metal for weight reduction without compromising its overall strength to weight ratio. Mg Alloys containing Zinc, Manganese and Aluminum were found to be suitable for automobile and aerospace applications and is also cheaper to produce. Aluminum improves cast ability. Stir casting is one of the most economical processes suitable for the production of metal alloys due to its simplicity. Zinc contributes towards improvement of strength at ambient temperatures. Manganese offers corrosion resistance, but has low solubility. Change in composition of an alloy could change its properties, depending on the property imparted by the metal. In this paper, the detailed characterization of magnesium alloys was analyzed and results showed that there is a significant improvement in mechanical and metallurgical properties in novel magnesium alloys.
