Metal
matrix composites are advanced materials that provide high mechanical strength,
superior thermal stability and wear resistance through ceramic, carbon or
metallic reinforcement phases dispersed within a metallic matrix; this
structure enables them to operate without performance loss in high-temperature
environments, surpassing the limitations of traditional metal alloys. Copper
matrix composites in this group are particularly noteworthy for maintaining
high thermal and electrical conductivity while also improving properties such
as hardness, fatigue resistance, and dimensional stability. Copper matrix
composites are widely used in areas requiring reliable performance under high
heat flow and mechanical loading, such as electrical contacts, heat sinks,
power electronics components, brake systems, welding electrodes, and aerospace
applications. The superior properties of these materials stem from the
synergistic combination of copper's natural conductivity advantage and the
mechanical reinforcement provided by the reinforcement phases (e.g., Al₂O₃,
SiC, graphene, W or Mo particles). ultimately forming a strategic solution for
contemporary engineering systems where both thermal and electrical
functionality and mechanical strength are critical. In this study,
investigations were conducted on the particle size distribution and powder
morphologies of Cu-SiC-Gr nanocomposite powders obtained by mechanical alloying
with nano-sized SiC and graphene reinforcement in copper powders used as matrix
material.
