Experimental Investigation of Silicon Carbide Nanoparticles Reinforced Magnesium Alloy (AZ91E) Metal Matrix Composite by Vacuum Stir Casting Method 2019-28-0169
In the present investigation silicon carbide nanoparticle reinforced magnesium alloy (AZ91E) composites were prepared by vacuum stir casting process in an inert atmosphere. Required amount of silicon carbide nanoparticle was added to AZ91E molten melt with constant stir speed of 600 rpm and vacuum pressure of 1 lpm so that the final composite contains 5, 7.5 and 10 wt.% SiC nanoparticle. The prepared composite was subjected to mechanical and microstructure studies. The addition of silicon nanoparticle enhances the mechanical properties compared to conventional magnesium alloy. Microstructure studies reveal uniform distribution of silicon carbide in magnesium alloy matrix.
