Additional Al4C3 may form during melt processing through direct contact between the melt and carbonaceous materials.
mp-1591: Al4C3 (trigonal, R-3m, 166) - Materials Project
网页Al4C3 is Aluminum carbonitride-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four equivalent C4- atoms to form a mixture of corner and edge-sharing AlC4 trigonal pyramids.
Exploring the size effects of Al4C3 on the mechanical properties …
网页2018年8月1日 · The role of Al 4 C 3 on the mechanical properties of Al based composites reinforced by SiC particles and CNTs is size dependent, i.e., nanosized Al 4 C 3 helps to increase the interface shear stress and improves the strength of composites, while micro-scale Al 4 C 3 significantly deteriorates the mechanical properties.
Structural, Electronic and Vibrational Properties of Al4C3
网页2019年4月30日 · Abstract. Al 4 C 3 single crystals are synthesized by the reaction between SiC and aluminum and are structurally verified and analyzed by Raman and X-ray diffraction spectra. The optical absorption measurements of the Al 4 C 3 crystals indicated that the bandgap is about 2.3 eV, which surprisingly is much higher than …
