Carbon-based nanomaterials mainly including carbon nanotubes (CNTs), graphene, and graphene oxide (GO) have superior properties of low density, outstanding strength, high hardness. Compared with ceramic reinforcements, small amount carbon-based can significantly improve the mechanical metal matrix composites (MMCs) (CMCs). However, CNTs graphite always aggregate or degrade during fabrication a ...

In this study, multi wall carbon nanotubes (MWCNTs) were synthesized by Chemical vapor deposition (CVD) method using two different catalysts (Fe nanoparticles) and (Ni nanoparticles) with  two different substrates: Quartz and Alumina. Acetylene gas was used as a carbon source and Argon as a carrier gas at different temperatures and different times to study the effects of these parameters on CNT...

The present paper aims to investigate the solidification behavior and the forgeability of Aluminum alloy (LM6)-SiCp composites at different section of three-stepped composite castings. The temperature of the cast composites during solidification has measured by putting K-type thermocouples at the center of the each step/section, from which the solidification curves were constructed. The forgeab...

At present, material properties are being continuously improved in line with current technological developments to meet operational and safety standards. Designers consumers now look for materials that more energy effi- cient, stronger, lighter as well cheaper. A metal-matrix composite (MMCs) will represents a dominant class of which can be suitably designed the above requirements. With variety...

in this study, ultrafine grained 2024 al alloy based b4c particles reinforced composite was produced by mechanical milling and hot extrusion. mechanical milling was used to synthesize the nanostructured al2024 in attrition mill under argon atmosphere up to 50h. a similar process was used to produce al2024-5%wt. b4c composite powder. to produce trimodal composites, milled powders were combined w...

The performance characteristics of metal matrix composites (MMCs) and the need to study their fretting fatigue wear during service are discussed. Four main elements MMCs (aluminum, copper, titanium, iron, magnesium, nickel, etc.) These factors influencing fatigue, mechanism research, life prediction, development process protection methods, respectively. Factors such as internal crack nucleation...

High-entropy alloy particles (HEAPs) can markedly enhance the mechanical properties of metal matrix composites (MMCs). In this study, AA5083/Al0.5CoCrFeNi HEAPs MMCs with different contents (0, 1, and 3 wt%) were prepared via a stir-casting, then these sheets hot rolled (573 K) cryorolled (77 K), respectively. The measured by tensile testing microhardness test. Additionally, their microstructur...

High modulus of about 1 TPa, high thermal conductivity over 3000 W/mK, very low coefficient expansion (CTE), electrical conductivity, self-lubricating characteristics and density have made CNTs one the best reinforcing materials nano composites for advanced structural, industrial, strength wear-prone applications. This is so because it has capacity improving mechanical, tribological, electrical...
