Impact of Graphite on Aluminum Alloy 6061: Insights into Mechanical and Tribological Behavior Through Hot Press Forging
This study investigates the effects of graphite particle reinforcement on the mechanical and tribological properties of aluminum alloy AA6061 composites produced via hot press forging (HPF), a direct recycling method for aluminum chips. Graphite content varied from 2.5% to 12.5%, with the Al6061-7.5%Gr composite achieving the highest tensile strength (102.36 MPa) and yield strength (87.07 MPa). Hardness peaked at 24.73 HV with 5% graphite. Tribological tests showed improved wear resistance at higher graphite levels, with the Al6061-12.5%Gr composite exhibiting the lowest wear rate (0.00033 mm<sup>3</sup>/N·m). These findings highlight HPF’s potential for sustainable fabrication of high-performance aluminum composites.
