“…It is well known that the particle-reinforced metal matrix composites (MMCs) have excellent mechanical properties due to the addition of the high strength and high modulus particles [1] such as TiC [2], Al 2 O 3 , SiC [3], TiB 2 [4] , mica [5] etc. Extensive investigations were carried out on composites to evaluate properties like wear [3], tensile behavior, fracture toughness [6,7] and cyclic behavior [8] etc. There has been an increasing interest in composites containing low density and low cost reinforcements.…”

AA6061-fly ash particle composites were fabricated using cold pressing followed by hot extrusion. Composites containing 2, 6 and 10 wt.% fly ash particles were fabricated. Matrix alloy samples without fly ash content were also prepared for comparison. Optical microscopy, Xray diffractrometry, Scanning Electron Microscopy and Transmission Electron Microscopy were adopted for characterizing the composites. Uniform distribution of fly ash particles was observed in composites. Hardness and tensile strength of the 2 wt.% fly ash composite were found to be better compared to the monolithic alloy after age-hardening. However, further increase of fly ash content resulted in poor agehardening due to the depletion of Mg from the alloy matrix and transfer to the fly ash interface, which was confirmed by EDX analysis.

Metal Matrix Composites are engineered materials, produced by the combination of two or more different materials to gain improved properties. In the current analysis, an Al-4.5% Cu alloy be used as the fly ash and graphite and matrix is reinforcement. Aluminum copper alloy matrix composite repels the much concentration due to their high thermal conductivity, lightness, moderate making temperature etc. graphite powders and fly ash are used since its low density and high strength. The composite was formed using stir casting approach. The fly ash was added in 3%, 6%, and 9 % by weight and graphite was added in 3%, 6%, and 9 % by weight to the molten metal. The composite was tested for hardness, mechanical properties,. Microstructure investigation was done using a scanning electron microscope to gain the distribution of graphite and fly ash in the aluminum matrix. The results found an increase in tensile strength and hardness with increasing the graphite and fly ash content.

“…A variety of particles such as mica, Al2O3, graphite, and SiC have been used as reinforcement materials with aluminium alloys [4][5][6][7][8] as the matrices. It appears that stir casting is one of the methods for producing composites [1][2][3][4][5][6][7]. The use of fly ash as a reinforcement material [9] results in improvement of mechanical properties of the composite.…”

Metal matrix composites (MMCs) are engineered materials, formed by the combination of two or more dissimilar materials (at least one of which is a metal) to obtain enhanced properties. In the present investigation, anAl-4.5% Cu alloy was used as the matrix and fly ash as the filler material, graphite is reinforcement. In the present, aerospace, automobile industries, replacing the existing metal matrix composites from Al 6061 to its high performance application. Aluminum copper alloy matrix composite attracts the much attention due to their lightness, high thermal conductivity, moderate casting temperature etc. fly ash and graphite powders are used because of its high strength, high hardness, less density.The composite was produced using stir casting method. The fly ash was added in 3%, 6%, and 9 wt. % and graphite was added in 3%, 6%, and 9 wt. % to the molten metal. The composite was tested for fluidity, hardness, density, mechanical properties, Microstructure examination was done using a scanning electron microscope to obtain the distribution of fly ash and graphite in the aluminium matrix. The results show an increase in hardness, tensile strength with increasing the fly ash and graphite content. The density decreases with increasing fly ash content. Corrosion increases with increasing fly ash content. Specimen is fabricated at different weight percentages and to be carried out for mechanical properties.
