Fabrication of aluminum carbide nanowires by a nano-template reaction

Rapid, energy-efficient synthesis of the layered carbide, Al4C3

“…Up to the present time, only a small number of reports referring to the synthesis and application of the phase have been published. [1][2][3][4][5][6] Al4C3 has a layered rhombohedral structure (R3 ̅ m) composed of alternating Al2C and Al2C2 layers. 7 Aluminium carbide often arises as an undesired degradation product which can have a significant negative impact on SiC-Al and carbon-fibre composites.…”

FEA evaluation of the Al4C3 formation effect on the Young’s modulus of carbon nanotube reinforced aluminum matrix composites

“…This fact results in significantly different mechanical properties of the composites, as the strength and thickness of the carbides determine the stress that could be transferred to the CNT. The reported thickness of the carbide layer differs: Bakshi et al [9] found that it is approximately 6 nm for the Al-11%Si alloy, being the critical value for Al 4 C 3 formation approximately 0.65 nm at 1700 K; while He et al [1] obtained Al 4 C 3 nanowires with diameters ranging from 7 to 25 nm. Growing of Al 4 C 3 is possible by two mechanisms: the perpendicular or the lateral growth of the carbide.…”

“…The use of carbon nanotubes (CNT) as reinforcing material has originated a new class of composites with many applications due to their attractive lightweight and high mechanical and thermal properties [1][2][3]. Several reports have investigated the use of CNT reinforced composites, mainly focused on polymer matrix composites [4,5].…”

“…Several reports have investigated the use of CNT reinforced composites, mainly focused on polymer matrix composites [4,5]. Nevertheless, there has been comparatively little research related to CNT reinforced metal matrix composites (MMC) [1,2,[6][7][8][9], being the interfacial bonding between CNT and matrix one of the topics that needs further attention because of the different carbides formed and their characteristics, which have important effects on the mechanical behavior of these materials. Different techniques have been used to examine the mechanical properties of composites in the immediate vicinity of reinforcing CNT, including Scanning Electron Microscopy, Transmission Electron Microscopy and Scanning Probe Microscopy [1,7].…”

It has been experimentally established the importance of the interface: a strong interface would make the composite very strong but at the expense of affecting the magnitude of ductility, while a weak interface would lead to a lower strength and inefficient utilization of CNT properties.…”
