Aluminum matrix composites (AMCs) reinforced with novel carbon nanotube (CNT)-Fe-based metallic glass (FMG) synergistic reinforcements were successfully prepared by powder metallurgy. The CNT-FMG reinforcements were obtained by growing CNTs on the surface of FMG particles using chemical vapor deposition (CVD). By controlling the catalytic temperature, the grown CNTs exhibited good morphology, a high degree of graphitization, and thermal oxidation stability. CNTs were homogeneously dispersed in the Al matrix through the carrying action of FMG particles. The CNT-FMG synergistic reinforcements significantly improved the mechanical properties of the composite, and formed a tight interfacial bonding with the Al matrix. The CNT-FMG reinforcements had a remarkable synergistic strengthening effect on the composite. •CNTs were grown on the surface of FMG particles by chemical vapor deposition.•CNT-FMG synergistic reinforced Al matrix composites were prepared.•CNTs were homogeneously dispersed in Al matrix through the carrying of FMG.•CNT-FMG contributed remarkable synergistic strengthening effect to the composite.
