Abstract Scope |
This study investigates the microwave casting of copper-based composites reinforced with 5 wt% silicon carbide (SiC) particles, focusing on microstructural and mechanical properties. Microwave heating at 2.45 GHz and 900 W assisted the casting of pure copper in 7 minutes, while SiC-reinforced composites melted even faster, within 5 minutes. Microstructural analysis revealed hexagonal grains, indicating uniform SiC distribution within the copper matrix. X-ray diffraction (XRD) confirmed the presence of Cu₆₄O phases. The Cu-5% SiC composite achieved a high relative density of 98.56% with porosity under 1%, suggesting excellent compaction and structural integrity. Vickers hardness testing showed a significant increase in hardness to 172.74 ± 89 HV, approximately 2.81 times that of pure copper, highlighting the strengthening effect of SiC reinforcement. |
