This work reports CNT-reinforced AI nanocomposites fabricated with in situ chemical vapor deposition process for achieving homogeneous dispersion of CNTs and good interfacial bonding between CNT and metallic matrices. The mechanical strength of CNT/Al nanocomposites is dependent on CNT addition, while the fracture straindegrades compared with that of pure metal. The good reinforcement of CNT/metal nanocomposites is attributed to the strong interfacial bonding as well as the homogeneous dispersion of CNTs in the matrix. Furthermore, the strong interfacial bonding is due to the existence of transition thin layer of Al4C3 between CNTs and Al matrix. (C) 2009 Elsevier B.V. All rights reserved.
