How do ceramic particles strengthen metallic copper?

Publishing in the International Journal of Extreme Manufacturing, scientists from Jilin University and Edith Cowan University comprehensively reviewed the latest preparation techniques of copper matrix composites and the effect of ceramic particles on the mechanical properties, thermal conductivity and thermal expansion behavior of the composites. Four main aspects of particle characterization were included: particle content, particle size, particle morphology and interfacial bonding of particles to copper matrix.
