“…These knots can act as structural anchors and result in mechanical interlocking between the matrix and BNNTs, and thus enhance the interface bonding. It also agrees with the reported results about other nanotubes or nanowires with similar morphology [18][19][20][21]. On the other hand, the interface bonding is also strengthened by the thermal residual clamping stress exerted on the interface [22][23][24].…”

Effect of BNNTs/matrix interface tailoring on toughness and fracture morphology of hierarchical SiCf/SiC composites

et al. 2019

A thin BN interphase is applied on BNNTs surface to tailor the interfacial bonding between BNNTs and SiC matrix in hierarchical SiC f /SiC composites. The thickness of BN interphase ranging from 10 to 70 nm can be optimized by chemical vapor deposition after BNNTs are in situ grown on SiC fiber surface. Without BN interphase, the fracture toughness of hierarchical SiC f /SiC composites can be impaired by 13.6% due to strong interfacial bonding. As long as BN interphase with 30-45 nm thickness is applied, the interfacial bonding can be optimized and fracture toughness of hierarchical composites can be improved by 27.3%. It implies that tailoring BNNTs/matrix interface by depositing a layer of BN interphase is in favor of activating energy dissipation mechanisms at nanoscale induced by BNNTs.

“…However, the limitations of stir casting are poor distribution, wettability, porosity, interfacial reaction and moderate volume fraction [12]. Generally, pressure infiltration method is an effective technique to fabricate poor-wetting system through forcing infiltration of molten metal alloy into the preform under high pressure, and the main advantages of pressure infiltration method include simplicity in preparation process, high quality (especially high relative density) in composites and no restrictions on the composition of the matrix alloys [19][20][21].…”

In the present work, the wire electrical discharge machining (WEDM) process of the 65 vol% SiCp/2024Al composite prepared by pressure infiltration methods has been investigated. The microstructure of the machined composite was characterized by scanning electron microscope, the average surface roughness (Ra), X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy (TEM) techniques. Three zones from the surface to the interior (melting zone, heat affected zone and unaffected zone) were found in the machined composites, while the face of SiC particles on the surface toward the outside was ''cut'' to be flat. Increase in Al and Si but decrease in C and O were observed in the core areas of the removed particles. Si phase, which was generated due to the decomposition of SiC, was detected after the WEDM process. The irregular and spherical particles were further observed by TEM. Based on the microstructure observation, it is suggested that the machining mechanism of 65 vol% SiCp/2024Al composite was the combination of the melting of Al matrix and the decomposition of SiC particles.

The large-scale synthesis of high-purity SiC nanowires is a challenge. In this context, sponge-like graphene oxide (GO) was used as a carbon source as well as a reaction template for directly synthesizing SiC nanowires. GO was completely reacted with SiO to prepare high-purity 3C-SiC nanowires by thermal evaporation and carbothermal reduction without the use of any catalyst, rather than by epitaxy. Characterization was conducted using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and selected-area electron diffraction. The SiC nanowires had lengths of several tens of micrometers and a perfect single-crystalline structure with a bamboo-like morphology.
