| Abstract | ||
| The wide use of aluminum alloy in the aerospace and automotive industry is because of its excellent erosion resistance, formability, quality and light weight which is demanded in many industries. Herein, aluminum (Al-7075) composite is fabricated with the aid of stir casting method, nanofillers like boron carbide (B4C), aluminum dioxide (Al2O3) and Zirconia (ZrO2) were added to the composite. Nanoparticles of ZrO2 were added with different weight fraction of 2, 4, 6 and 8 wt. %. The B4C and Al2O3 nanoparticles were added to the aluminum composites with fixed ratio of 5 wt. % and 10 wt.%, respectively. The samples were fabricated according to ASTM E8M standards for tensile test. Hardness test specimens were prepared according to ASTM E10. Tests were carried out on the ceramic nanoparticles reinforced Al-7075 composites. The results cleared that the addition of nanofillers especially ZrO2 has significant enhancements on the mechanical properties of the metal matrix composites. | ||
