microstructure and mechanical property of multi walled carbon nanotubes reinforced Aluminum Matrix composites fabricated by friction stir processing
Materials & Design, 2013Co-Authors: Liming Ke, Chunping Huang, Li XingAbstract:Abstract Aluminum Matrix composites reinforced by different contents of multi-walled carbon nanotubes (MWCNTs) were fabricated by friction stir processing (FSP). The microstructure of nano-composites and the interface between Aluminum Matrix and MWCNTs were examined using optical microscopy (OM) and transmission electron microscopy (TEM). It was indicated that MWCNTs were well dispersed in the Aluminum Matrix throughout the FSP. Tensile tests and microhardness measurement showed that, with the increase of MWCNT content, the tensile strength and microhardness of MWCNTs/Al composites gradually increased, but on the contrary, the elongation decreased. The maximum ultimate tensile strength reached up to 190.2 MPa when 6 vol.% MWCNTs were added, and this value was two times more of that of Aluminum Matrix. Appearances and fracture surface micrographs of failed composite samples indicated that the composites become more and more brittle with the increase of the MWCNT content.

particle reinforced Aluminum Matrix composites produced from powder mixtures via friction stir processing
Composites Science and Technology, 2011Co-Authors: C F Chen, Newjin HoAbstract:Abstract Particle-reinforced Aluminum Matrix composites were produced from powder mixtures of Aluminum and silicon by using multiple passages of friction stir processing (FSP). In the composites, the Si particles with an average size of ∼1.5 μm are uniformly dispersed in the Aluminum Matrix which has a fine-grained structure (∼2 μm). The strengthening mechanism of the composites is discussed. It indicates that the fine grain size of Aluminum, the Orowan strengthening due to intragranular particles and the dislocations generated by thermal mismatch all contribute significantly to the composite yield strength.

reinforcement with carbon nanotubes in Aluminum Matrix composites
Scripta Materialia, 2008Co-Authors: Hyunjoo Choi, G B KwonAbstract:Aluminum Matrix composite rods in which tightly bonded multi-walled carbon nanotubes (MWNTs) are separately dispersed and uniaxially aligned have been fabricated by hot extrusion of ball-milled powders. The reinforcing efficiency of MWNTs in the composites follows the volume fraction rule of discontinuous fibers in the grain size range down to 70 nm.
