Metal Matrix Composites (MMCs) have drawn a lot of interest in the area of innovative materials because of how widely they may be used. Due to their extraordinary qualities, such as high thermal conductivity, higher temperature endurance, improved corrosion resistance, and great weldability, copper matrix composites stand out among them. These qualities make them desirable and promising materials for uses including heat exchangers, automotive parts, and electrical components.
In this investigation, Copper Matrix Metal Composites (MMCs) were processed by employing muffle furnace sintering techniques. The study documents enhancements in mechanical properties, specifically compressive strength and hardness, with an increase in the content of reinforcing materials. For this research, six distinct metal matrix composite specimens were fabricated, utilizing pure copper (Cu) as the base material. Each time, the copper was reinforced with silicon carbide (SiC), and graphite was added as a constant additive at a consistent volume fraction (5%). A powder state mixing technique was employed to combine the various constituents. Following the mixing process, the powders were introduced into metallic molds, and the specimens were subsequently sintered using a muffle furnace under an inert gas atmosphere at different temperatures (850 °C and 950 °C), with varying soaking times. Multiple tests, including hardness assessments, compressive strength measurements, and microstructure analysis, were conducted on the composite specimens. The results indicated that sintering at 850 °C resulted in the production of a more effectively fused matrix compared to rapid sintering at 950 °C, leading to significantly improved mechanical properties, particularly in terms of compressive strength. This improvement was particularly noticeable at 15% SiC with 5% graphite content when sintered at 850 °C.
