OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 3 2025 a b Fig. 5. Surface images without (a) and with (b) stirring for Specimen 7 Fig. 6. Elemental analysis of Specimen 7 (Al7075 + 0.5 % graphene + 3 % SiC) Fig. 7. Elemental analysis of Specimen 8 (Al7075 + 1% graphene + 2% SiC) distribution. Mechanical stirring reduces porosity and improves bonding, wetting, and cohesion between the matrix and reinforcements. These microstructural alterations likely contribute to the superior strength and toughness of stirred composites compared to unstirred ones. The study highlights that the implementation of appropriate mixing techniques can significantly influence the surface morphology and mechanical properties of Al7075 nanocomposites. Energy dispersive X-ray spectroscopy (EDX) analysis in this study confirms the homogeneous distribution of SiC and graphene nanoparticles within the aluminum matrix. Figs. 6 and 7 present the elemental analyses of Specimens 7 (Al7075 + 0.5% graphene + 3% SiC) and 8 (Al7075 + 1% graphene + + 2% SiC), respectively. The EDX analysis confirms the presence of SiC nanoparticles within the aluminum
