A three-dimensional network model for performing non-linear time-dependent simulations of the electrical characteristics related to a composite material is presented. The considered compounds are represented by a cubic lattice and consist of conducting particles distributed in an insulating matrix. Earlier studies of the non-linear characteristics of silicon carbide (SiC) grains and of the line...

al-sic composites are among the most demanding metal matrix composites due to their excellent strength, good ductility, good corrosion resistance, low coefficient of thermal expansion and reasonable price. manufacturing of cast metal matrix composites usually involves some problems such as inhomogeneous distribution of the particles due to poor wetability of ceramics to molten alloys, porosity ...

Flow in porous Silicon Carbide (SiC) has been investigated in order to increase the understanding of the determining parameters. Porous SiC is used in the fabrication of ceramic membranes, for use in cross-flow and dead-end filtration. Therefore, a description of the flow would help to design more efficient filtration modules, and to improve the use of the existing modules. The investigation pe...

Abstract A novel Y 3 Si 2 C material was synthesized at a relatively low temperature (900 °C) using molten salt method for the first time, and subsequently used as joining carbon fiber reinforced SiC (C f /SiC) composites. The sound near-seamless joints with no obvious remaining interlayer were obtained 1600 °C an electric field-assisted sintering technique (FAST). During joining, liquid phase ...

Ceramic reinforced friction stir spot-welding (FSSW) is one of the unique welding techniques used to fabricate spot joints. This study intended investigate effect reinforcement additive particle size in achieving higher weld strengths. AA5083-H116 aluminum alloy plates were welded with nano- and micro-sized silicon carbide (SiC) particles. Investigations joints prepared using a tool rotational ...

Silicon carbide (SiC) particles are exciting structures because of their hardness, chemical inertness, and dielectric properties. In particular, absorption/emission properties in the mid-infrared range render them suitable for ambient temperature thermal emitters. However, synthesis uniform, spherical is still challenging. Here, we present a robust procedure based on carbothermal reduction sili...
