Evaluating the Hardness and Microstructural Analysis of Reinforcing the Nano Silicon Carbide and Nano Zirconium Oxide in Hybrid Al6061 Metal Matrix Composite

Aluminium alloy (Al6061) matrix composite is reinforcing of β phase APS silicon carbide nanoparticle at scale range of 50 nm in the weight percentage of 2% along with β phase APS zirconium oxide of nanoparticle at 45 nm scale range in the weight % of 2.8, 3.0 and 3.2%. By progressing, the reinforcement element is carried out using the stir casting method to form the hybrid aluminium-based metal matrix nanocomposite samples. Microstructure and hardness properties are analysed in fabricated aluminium-based metal matrix nanocomposite samples. These metal matrix nanocomposites are characterized by scanning electron microscope (SEM). Hardness tests are carried out in order to identifying hardenability in the aluminium-based metal matrix nanocomposite. The results revealed that Al metal matrix nanocomposites are containing 2% of nano silicon carbide along with 3.2 wt% of nanoparticle of zirconium oxide (ZrO₂) samples to improve the hardness strength among the other samples of hybrid aluminium (Al6061) metal matrix nanocomposite.
