“…5. 20,21,39,43 EDS and XPS are problematic methods because low carbon concentrations and residual carbon within the microscope chamber can yield a "false positive" of carbon peaks. 12 Glow discharge mass spectroscopy and secondary ion mass spectroscopy (SIMS) detect trace carbon amounts that correspond to unconverted carbon.…”

“…Among the metals, aluminum-based materials are gaining interest because of their low densities. However, they have poor mechanical performance such as strength and rigidity compared to copper and iron based alloys [2]. Researchers have been trying to develop strength, stiffness, thermal, corrosion and wear resistance of aluminum matrix composites using traditional ceramic and fiber particles.…”

Aluminum matrix composites have attractive attention for scientists and manufacturers. In this study, fullerene (C60) nanoparticle reinforced aluminum matrix composite was fabricated via semi powder metallurgy method. Microstructure analyzes were completed by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). Hardness, compression and tensile properties of unreinforced aluminum and C60 reinforced composite were evaluated. Results show that nanoparticle was homogenously distributed in matrix and there were no cracks or macro defects. Hardness was significantly improved with the addition of fullerene and extrusion process. Al-C60 composite exhibited better compression and tensile performance than pure aluminum.

“…Bu durum, X-ışını kırınımı cihazının düşük hassasiyetinden ve çok katmanlı karbon nanotüpün düşük katkı oranından kaynaklanmaktadır. Ayrıca Al-KNT kompozit yapılarda Al4C3 (2θ=~37°, 41°, 43°, 48°, 51°, 56°, 61°, 67°) gibi istenmeyen ikincil bir faza rastlanmamıştır[20].…”

In this study, aluminum based composites reinforced with multiwalled carbon nanotube were produced by the powder metallurgy method. The effect of carbon nanotube amount (0.15, 0.30, and 0.45%wt.) on the microstructure, apparent density, porosity, compressive strength, and Vickers hardness of the aluminum based composites was examined. The powder metallurgy route consists of mixing, ultrasonic dispersing, drying, filtration, sintering, and pressing processes. The microstructure and crystal structure of specimens were examined by Xray diffractometer and scanning electron microscopy, respectively. The highest mechanical properties were obtained at aluminum based composite reinforced with 0.3%wt. carbon nanotube. The test results showed that the compressive strength, Vickers hardness, and apparent density of 0.3%wt. carbon nanotube reinforced aluminum based composites were improved by ~72%, ~38%, and ~2% compared with those of pure aluminum, respectively. It was detected that the strength of carbon nanotube reinforced aluminum based composites are thought to be deteriorated because of the segregation or accumulation clustering carbon nanotubes observed under the scanning electron microscope.
