Abstract :In this study, metal matrix hybrid composites obtained by adding B4C and graphene nanoplatelets insert ignore into journalissuearticles values(GNPs); powders as reinforcement elements to Al7075 powders were produced by powder metallurgy insert ignore into journalissuearticles values(P/M); method. Mixture powders prepared by supplementing Al7075 powders with different weight ratios of B4C insert ignore into journalissuearticles values(2-5-10%); and GNPs insert ignore into journalissuearticles values(0.5%); are compressed at room temperature and at different pressing pressures insert ignore into journalissuearticles values(600-700-800 MPa); and then at different temperatures insert ignore into journalissuearticles values(500-550- 600C); was sintered in vacuum atmosphere and samples were produced in accordance with ASTM G99 standard. Density and hardness analyzes were carried out depending on the changing production parameters of hybrid composites. It was determined that the pressing pressure had a direct effect on the condensation rate of the samples and the highest density value was 2.6764 g/cm3 in the Al7075+5% B4C+0.5% GNPs sample pressed under 800MPa pressure. The hardness of the samples, on the other hand, generally increased due to the increasing amount of reinforcement element, while it also increased with the increase of pressing pressure and sintering temperature.
