Synergistic strengthening mechanism of copper matrix composite reinforced with nano-Al2O3 particles and micro-SiC whiskers

Abstract

Copper matrix composites reinforced with nano-Al2O3 particles and micro-SiC whiskers were prepared. Nano-Al2O3 particles are uniformly dispersed in the copper matrix (Figure a), and there is an obvious amorphous transition layer at the interface between the copper matrix and SiCw (Figure d). Nano-Al2O3 particles and micro-SiC whiskers reinforcing phase synergistically strengthen the SiCw/Cu–Al2O3 composite.
