Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength and are increasingly seen as an alternative to conventional materials, particularly in the automotive industry. In this study, a historical background on the development and application of metal matrix composites for automotive brake rotors is presented. The dis...

Abstract The utilization of agro-residues ash as complementary reinforcing materials continues to gain prominence for metal matrix composite (MMCs) development. A rarely investigated but largely available among these is the palm kernel shell (PKSA). Thus, present study investigates influence PKSA particulates hybridized with SiC on physico-mechanical properties and microstructure Al6063 composi...

Aluminium—boron carbide metal matrix composites (Al-B4C MMCs) belong to the class of materials extensively used in nuclear industry as a thermal neutron absorber spent fuel casks. This article investigates novel production method Al-B4C MMCs—Friction Stir Additive Processing (FSAP)—as an alternative casting or sintering. FSAP is derived from friction stir welding, which can be local modificatio...

Al/SiC functionally graded and metal-matrix composites were investigated through dynamic mechanical analyzer as a function of vibrating frequencies. It was found that internal frictions strongly dependent on material type frequency. Tan ? reached 30.4 × 10–3 21.2 10–3in FGM MMC, respectively, at frequency 1 Hz. The damping capacity decreased the increased to 10 Hz 30 Storage moduli 172 GPa 144 ...

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 paper attempts to study the machinability issues of aluminium-silicon carbide (Al-SiC) metal matrix composites (MMC) in turning using HSS cutting tool. SiCp-reinforced metal matrix composites (MMCs) containing SiC particles (5wt%-20wt %) of 400mesh size were prepared by powder metallurgy (P/M) route and used as work material for turning. Experiments were conducted at various cutting speeds ...

Development of aluminium composites by stircasting technique is an effective method for fabrication better quality MMCs. Stircasting one the most commonly accepted techniques. In this research work, Al6061 / TiB2+CeO2 hybrid MMCs have been fabricated with varying wt. % TiB2 (2.5%, 5%, 7.5% and 10%) particulates constant 5% CeO2 particulates. The monolithic alloy composite were hot-rolled at a t...

Discontinuously reinforced aluminum metal matrix composites (MMCs) with about 20 vol.% reinforcement produced by powder metallurgy (PM) are attractive for many structural applications because of their high specific strength and stiffness. While they exhibit reduced ductility and toughness at room temperature, many of them can be superplastically deformed at high-strain rates in the vicinity of ...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...
