Aluminum/carbon nanotube (CNT)composites have been fabricated by a combination of spark plasma sintering and hot-extrusion processes. The CNTs were well dispersed onto Al particles by 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 good contact between CNT and aluminum matrix. As a result, the composites exhibited three times larger tensile strength than pure aluminum because of the effective load transfer from the matrix to the CNTs.

铝/碳纳米管（CNT）复合材料是通过放电等离子烧结和热挤压工艺相结合制造的。通过纳米级分散方法将CNTs很好地分散到Al颗粒上。通过放电等离子烧结和随后的热挤压制备高致密化的碳纳米管复合材料。通过光学、场发射扫描电子和高分辨率透射电子显微镜的微观结构观察证实，烧结的Al/CNT致密和挤压块体材料具有良好的取向CNT分散性。拉曼光谱表明加工抑制了对碳纳米管的损伤。 SPS 烧结过程中形成少量瞬态铝液相，这有助于致密化以及 CNT 和铝基体之间的良好接触。结果，由于负载从基体到碳纳米管的有效转移，复合材料的拉伸强度是纯铝的三倍。
