Improved Mechanical Properties of AA5083 Reinforced with Multiwall Carbon Nanotubes for Automobile Applications
Main Article Content
Abstract
Aluminium alloys are widely used in automobile applications due to their good mechanical, corrosion and wear resistance properties. This work mainly focuses on the enhancement of mechanical properties of Aluminium alloy AA5083/MWCNT composites using a semi-solid state route (compo-casting method) and compare with the conventional AA5083 alloy. AA5083 and MWCNT microstructures were examined using field emission scanning electron microscope and energy-dispersive X-ray spectroscopy analysis. The experimental results showed an enhancement in the ultimate tensile strength and yield strength for the MWCNT reinforced composite compared to the corresponding values of AA5083. The Brinell Hardness of the MWCNT reinforced composite was better than the conventional AA5083.
