abstract = "Aluminum /carbon nanotube (CNT) composites with nanoscale dispersion and regular orientation of CNTs have been fabricated by a combination of spark plasma sintering and hot-extrusion processes. The CNTs were well dispersed onto Al particles by a nanoscale dispersion method. The highly densified CNT composites were prepared by spark plasma sintering and subsequent hot extrusion. Microstructural observations by optical, fieldemission scanning electron and high-resolution transmission electron microscopies confirmed that the sintered Al/CNT compact and extruded bulk material has a good dispersion of oriented CNTs. Raman spectroscopy showed that the processing restrained damage to the CNTs. A small amount of transient Al liquid phase was formed during SPS sintering, which may assist the densification as well as local formation of Aluminum carbides on the CNTs. As a result, the composites exhibited three times larger tensile strength than pure aluminum because of the reinforcement of the CNTs.",
