In the present study, AlA380-based nanocomposites reinforced with graphene nano sheets (0.25, 0.5, 0.75 and 1% volumetric) were fabricated using the Spark Plasma Sintering Furnace (SPS) technique in vacuum at 540 °C. Microstructural and mechanical properties of the AlA380-GNPs nanocomposites were investigated as a function of the GNPs reinforcement percentage. It was found that adding 0.75% GNPs increased the hardness of the SPS samples from 50 HV for AlA380 matrix to almost 70 HV for AlA380%-0.75% GNPs nanocomposite. OM and SEM analysis were used to investigate microstructures of the nanoparticle distribution in the nanocomposites of the SPS samples. Results showed a considerable change in morphology after adding GNPs nanoparticles leading to an improvement in strength of the nanocomposite. In the end, the AlA380%-0.75% GNPs nanocomposite sample represents the greatest hardness and good microstructure to compare with the other experimented samples.
