The influences of graphene content (0.15-0.45wt.%), heat treatment (sintering and induction hot-pressing), and matrix material (Al2024, Al6061, and Al7075) on the mechanical strength and microstructure of specimens were studied. Compared to Al2024, Al6061 and Al7075 alloys, the compressive strength of Al2024-0.15graphene, Al6061-0.15graphene and Al7075-0.15graphene composites increased by 33.74%, 24.9% and 32%, respectively. The highest compressive strength (506±5 MPa), hardness (164±1.5 HV), and apparent density (2.65 g/cm3) were achieved in sintered and induction heat-treated Al7075-0.15%graphene composite. As a result, it was determined that graphene is an effective reinforcement element. It has been determined that induction hot-pressing improves the mechanical strength of composite materials.}, number={4}, publisher={Gazi University}, organization={This work was supported by the Scientific Researched Project Department of Ondokuz Mayıs University under Grant No. PYO.MUH.1901.22.008.}
