Effect of increasing corundum on mechanical properties of silicon carbide refractories
Oxide materials such as Al2O corundum has a great influence on the mechanical and oxidation properties of refractory or refractory materials. In this paper, the effect of Al2O3 powder density, apparent porosity, linear shrinkage, and oxidation resistance of SiC composite refractory materials is investigated. Meanwhile, the compressive and flexural strengths were investigated before and after he...
متن کاملMechanical properties of silicon carbide nanowires: effect of size-dependent defect density.
This paper reports quantitative mechanical characterization of silicon carbide (SiC) nanowires (NWs) via in situ tensile tests inside scanning electron microscopy using a microelectromechanical system. The NWs are synthesized using the vapor-liquid-solid process with growth direction of ⟨111⟩. They consist of three types of structures, pure face-centered cubic (3C) structure, 3C structure with ...
متن کاملMechanical Properties of Silicon Nanowires
Nanowires have been taken much attention as a nanoscale building block, which can perform the excellent mechanical function as an electromechanical device. Here, we have performed atomic force microscope (AFM)-based nanoindentation experiments of silicon nanowires in order to investigate the mechanical properties of silicon nanowires. It is shown that stiffness of nanowires is well described by...
متن کاملMechanical Properties of Amorphous Silicon Carbide
Excellent physical and chemical properties make silicon carbide (SiC) a prominent candidate for a variety of applications, including high-temperature, high-power, and high-frequency and optoelectronic devices, structural component in fusion reactors, cladding material for gas-cooled fission reactors, and an inert matrix for the transmutation of Pu(Katoh, Y. et al., 2007; Snead, L. L. et al., 20...
متن کاملInvestigation of the Physical and Mechanical Properties of Silicon Carbide Prepared on an Industrial Scale
In this study, an industrial polycrystalline SiC tile was successfully sintered by pressureless sintering at 2150°C for 1 hour. The physical and mechanical properties of silicon carbide including density, hardness, bending strength, and fracture toughness were evaluated. The results indicated that the mentioned properties were 3.08 g.cm-3, 2503 HV0, 249.3 MPa, and 1.23 MPam0.5</...
