| چکیده | ||
| This study examines the mechanical and physical properties of copper-graphite-silicon carbide (Cu-Gr-SiC) metal matrix composites (MMCs), focusing on parameters such as density, micro-hardness, compressive strength, flexural strength, and EDX analysis. Composites were developed using 5 wt.% graphite and varying SiC content (0–15 wt.%), using powder metallurgy techniques. The sintered density decreased from 8.23 g/cc for pure copper to 6.09 g/cc for the composite with 15 wt.%SiC, attributed to the lower densities of the reinforcing phases. Micro-hardness increased from 56 HV to 74.2 HV with rising SiC content, reflecting the hardening and grain refinement effect of SiC. Flexural strength reached a maximum of 200 MPa at 15 wt.%SiC, while compressive strength improved up to 5 wt.% SiC but declined at higher concentrations due to increased brittleness. EDX analysis confirmed uniform dispersion of reinforcements with minimal oxidation. These results support the use of Cu-Gr-SiC MMCs in demanding applications, with an optimal balance between reinforcement and mechanical performance. | ||
