in this research the influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistors were investigated. sic was added with amounts of 10-0 mass% to zno-based varistor composition. it is found that sic allows reaching to high threshold voltage with formation of fine-grained zno.another important effect of adding sic is formation zn2sio4 (willemite) on the ...

Understanding the role of nanoparticles in magnesium (Mg)-based materials and protective coating provides valuable information to achieve an optimized combination mechanical corrosion protection properties Mg nanocomposites. The present study investigates effects SiC on behavior structure Mg-SiC composites substrates coated by plasma electrolytic oxidation (PEO). Moreover, influence different v...

Abstract Novel MoAlB composites reinforced with 5–15 vol% SiC have been firstly prepared and characterized in the present study. The reinforcement is stable at a sintering temperature of 1200 °C Ar. 5 SiC/MoAlB composite exhibited improved mechanical properties enhanced oxidation resistance. A flexural strength 380 MPa Vickers hardness 12.7 GPa were achieved increased by 24% 51%, respectively, ...

The Al2O3-SiC reinforced Al7075 Metal Matrix Composite (MMCs) is fabricated through liquid metallurgical technique. Ceramic particulates were amalgamated into aluminium alloy to achieve improved mechanical properties and wear resistance. Al-7075/Al2O3/SiC hybrid MMCs produced by reinforcing 2%, 3%, 4% 5% of Al2O3 7% SiC particles. Microstructural analysis was carried out evaluate the uniform di...

In this paper, in situ SiC-reinforced Al-Zn-Mg-Cu composites were fabricated by laser powder bed fusion (LPBF). The effects of SiC content on the microstructure, phase composition, microhardness, and wear resistance as-printed preliminarily investigated. Results show that microstructure was regulated, matrix grains refined, tendency to orientation grain growth suppressed. particles reacted with...

A systematic investigation of structural, mechanical, anisotropic, and electronic properties of SiC₂ and SiC₄ at ambient pressure using the density functional theory with generalized gradient approximation is reported in this work. Mechanical properties, i.e., the elastic constants and elastic modulus, have been successfully obtained. The anisotropy calculations show that SiC₂ and SiC₄ are both...
