Abstract Functionally graded carbon nanotube (CNT)‐reinforced aluminum (Al) matrix composites have been successfully fabricated by a powder metallurgy route. The gradient layers containing different amounts of CNT additions showed microstructures and hardness. Each layer demonstrated good adhesion, with no serious pores or microcracks. We controlled the characteristics bulk composite efficient design each layer. functionally material concept offers feasible approach to fabricating Al‐CNT...
Carbon nanotube (CNT) reinforced aluminum (Al) matrix composite materials were successfully fabricated by mechanical ball milling followed powder hot extrusion processes. Microstructural analysis revealed that the CNTs well dispersed at boundaries and aligned with direction in composites obtained. Although only a small quantity of added to (1 vol%), Vickers hardness tensile strength significantly enhanced, an up three-fold increase relative pure Al. From fractography extruded Al–CNT...
A state‐of‐the‐art solid‐state lighting (SSL) device comprises a blue light‐emitting covered with yellow‐emitting phosphor. In high‐power SSL device, thermal stability is an essential requirement for the phosphor because constantly irradiated light, which causes degradation. this work, thermally robust phosphor–aluminum composite (PAC) fused low‐melting glass introduced. The PAC exhibits high conductivity of 31.6 W m −1 K and combined 4 laser diode (LD) excellent in luminous flux...
Aluminum (Al) matrix composite materials reinforced with carbon nanotubes (CNT) and silicon carbide nanoparticles (nano-SiC) were fabricated by mechanical ball milling, followed hot-pressing. Nano-SiC was used as an active mixing agent for dispersing the CNTs in Al powder. The hardness of produced composites dramatically increased, up to eight times higher than bulk pure Al, increasing amount nano-SiC particles. A small quantity aluminum (Al4C3) observed TEM analysis quantified using x-ray...
Aluminium-copper composite materials were successfully fabricated using spark plasma sintering with Al and Cu powders as the raw materials. Al-Cu through a ball milling process, effect of content was investigated. Composite composed Al-20Cu, Al-50Cu, Al-80Cu (vol.%) sintered by which carried out at 520 °C 50 MPa for 5 min. The phase analysis X-ray diffraction (XRD) energy-dispersive spectroscopy (EDS) indicated that intermetallic compounds (IC) such CuAl2 Cu9Al4 formed reactions between...
The high-temperature properties of titanium carbide (TiC)–reinforced stainless steel (SS) matrix composite, fabricated through infiltration process, were investigated across different temperatures. By adding highly concentrated and closely adjacent TiC particulate reinforcement, dramatic variations in the coefficient thermal expansion (CTE) conductivity properties, which originate from phase transformation SS matrix, effectively suppressed. Moreover, addition significantly strengthened SS,...
Multi-walled carbon nanotubes (MWCNTs) with outstanding mechanical properties are considered as an ultimate reinforcement for conventional metals such aluminum (Al), though they require uniform dispersion and intimate contacts the host metal matrix. However, bundled structure of chemically stable, pristine MWCNTs has been main challenge to achieving expected structural reinforcement. In addition, sole contribution in strengthening matrix not recognized yet, due concurrent mechanisms metal's...
Multi-walled carbon nanotube (MWCNT) reinforced copper (Cu) matrix composites, which exhibit chromium (Cr) carbide nanostructures at the MWCNT/Cu interface, were prepared through a formation using CuCr alloy powder. The fully densified and oriented MWCNTs dispersed throughout composites spark plasma sintering (SPS) followed by hot extrusion. tensile strengths of MWCNT/CuCr increased with increasing content, while strength composite decreased from that monolithic Cu. enhanced is result...
