摘要	A novel solution-assisted wet mixing processing was developed to efficiently produce CNT/Al composite powders. CNTs were firstly dispersed in zwitterionic surfactant aqueous solution, and then the flaky Al powders, produced from spherical Al powders by ball milling, were mixed with the CNT solution to adsorb the dispersed CNTs in the solution. It was indicated that CNTs could be uniformly adsorbed onto the flaky Al powders and CNT/Al powders with a maximum CNT concentration of 7.5 vol% could be obtained after filtering and drying. 1.5 and 3 vol% CNT/Al composites were then fabricated using the resultant composite powders through a powder metallurgy route. CNTs with average lengths of 0.9 mu m and well-retained wall structure were uniformly dispersed in the Al matrix and aligned arrangement of CNTs was achieved after hot forging. Furthermore, it was found that most of CNTs were distributed at the grain boundaries and the CNT-Al interfaces were well bonded. The strengths of the CNT/Al composites were significantly increased, which could be attributed to the efficient load transfer of CNTs. (C) 2016 Elsevier Ltd. All rights reserved.
