Fabrication and Characteristization of Bagasse Ash Particle (BAP) Reinforced Magnesium (AZ91E) Alloy Composite by Vacuum Stir Casting

Abstract

The present study is to fabricate AZ91E alloy matrix composite by varying the Bagasse ash particle (50μm) content (0, 5, 7.5, and 10wt%) via vacuum stir casting technique. The samples were characterized for its mechanical and microstructure properties. The mechanical properties of BAP reinforced composites were evaluated as per the ASTM standard and compared to unreinforced AZ91E alloy. The effect of reinforcement and distribution of BAP has been examined through a scanning electron microscope. The results of AZ91E magnesium alloy with 10wt% of BAP have found to have maximum tensile strength. The impact strength and hardness shows a marginal increase with increasing bagasse ash particle.

Conservation of waste melon shell and fly ash utilized as reinforcements for aluminum alloy matrix in terrestrial ecosystem acquired green hybrid composites

“…The externally preheated melon shell and fly ash particles with 50 μm coarse size feed into the furnace crucible maintained at the temperature of 550°C. A similar viscosity is retained during the complete mixing of aluminum alloy molten metal/melon shell ash/fly ash via 500 rpm continuous stir action help to increase the particle distribution results and attain good mechanical and tribological properties (Thirugnanasambandham & Chandradass, 2020; Rajan et al., 2007). The even mixed molten metal constitutions are transferred into the mold box and form the green metal casting size of 100 mm × 100 mm × 20 mm.…”

“…The sugar cane wastage of bagasse ash used as reinforcement for aluminum alloy found increased the mechanical and thermal performance of composite (Hassan & Aigbodion, 2010). The same way waste bagasse used magnesium alloy (AZ91E) composite was developed by vacuum stir casting route to enhanced hardness and strength of 83.33 Hv and 213.99 MPa, respectively (Thirugnanasambandham & Chandradass, 2020). The industrial waste fly ash prepared aluminum alloy composite observed high tensile strength in structural applications (Rajan et al., 2007).…”
