Özet

In the present work, nano alumina (Al2O3) reinforced aluminum (Al) matrix composites with various aluminacontent (0-2.5wt.%) were fabricated by powder metallurgy method. This method consists of mixing, ultrasonicdispersion, filtering, drying, pressing, and sintering processes. The effects of nano alumina amount on theVickers hardness, apparent density, compressive strength, and microstructure of nano alumina reinforcedaluminum matrix composites were investigated. The maximum apparent density (2.66 g/cm3), Vickers hardness(43±1 HV), and compressive strength (130±3 MPa) were determined at Al-2wt.%Al2O3 composite. After 2wt.%nano alumina content, the agglomeration was detected by a scanning electron microscope (SEM). Thisagglomeration deteriorated the mechanical properties of nano alumina reinforced aluminum matrix composites.
