Aluminium alloys are widely used in aerospace and automobile industries due to high strength to low weight ratio and their good mechanical properties such as better corrosion resistance and wear resistance, low thermal expansion as compared with other metals. The main objective of our work is to improve the mechanical properties such as impact strength, hardness of Aluminium based Metal Matrix Composite (MMC), and its relation with processing of the silicon carbide particulate (SiCp) as reinforced in Aluminum matrix. AA6061 alloy is chosen as matrix alloy, in which Aluminum is the base element. The work has been proposed for four different weight proportions of SiCp to aluminium matrix and the processing of the metal matrix composite is to be processed with stir casting setup and heat treated.

In the present scenario, composites are in huge demand in the industries due to their light weight, wear resistance, stiffness and high strength. The functional and structural properties were improved according to the need of industry. Particulate reinforcement is one of the methods to enhance the strength, ductility and toughness of the composites. Stir casting or friction stir processing technique was used to fabricate the metal matrix composite. For technology seekers it is very difficult to select appropriate techniques because there is lack of bench mark standards and industry experiences. The novel contribution of this paper is to provide systematic approaches and methodology which enable academic user as well as industry persons to select appropriate method and parameters for the fabrication of the metal matrix composite. This study guides the new researchers to fabricate and characterize the mechanical properties of aluminium-based composites reinforced with Al2O3, B4C, SiC, TiC, graphite and TiB2 particles.

Hybrid Metal Matrix Composite

The composite material is a combination of two or more materials with different physical and chemical properties. The composite has superior characteristics than those individual components. A hybrid composite is the one which contains at least three materials. When the matrix material is a metal, the composite is termed as metal matrix composites (MMC). The MMC is a composite material with two constituent parts, one being a metal. The other material may be another metal, ceramic or fiber. Among all the MMC’s, Aluminium is the most widely used matrix material due to its light weight, high strength and hardness. This paper deals with the fabrication and mechanical investigation of hybrid metal matrix composite Al - SiC. The fabrication is done by stir casting by adding the required quantities of additives into the stirred molten Aluminium. The results show significant effect of mechanical properties such as tensile strength, yield stress and flexural strength. The internal structure of the composite is observed using Scanning electron microscope (SEM) and found that are formation of pores in them.

Metal matrix composite is considered in various engineering fields like Automobile, medical, electronics aerospace, marine, recreational sectors, of which Aluminum metal matrix composite is considered mostly because of its high strength to weight ratio, easy of fabrication, corrosion resistance, good aesthetic appearance and high resistance to wear etc. This paper concentrates on the effect of secondary processing (Cold Extrusion) on mechanical and wear properties of Al6063 reinforced with SiC, Al2O3 and CeO2 particles. Here composite systems prepared by varying reinforcement from 0% to 8% in steps of 2%. Stir casting route adopted for casting composite systems after casting the composite is made to pass through extrusion process with an extrusion ratio of 1.93 with a total strain of 1.45. All composite systems tested for mechanical properties as per ASTM and ISO standard. Wear test was conducted on pin on disc setup for different loads, reinforcement, sliding distance and sliding speed. Results reveals that due increase in reinforcement the mechanical properties have improved further improvement observed when subjected to extrusion process, similar observation was made for wear studies which conclude the wear rate is improved for extruded composite as compared to cast composite systems observed by various researchers.

The application of Aluminium alloys becomes significant and most wide in the field of aviation industry. Aluminium 6061, because of its pro mechanical characteristics. Graphene is one of the allotropic forms of Carbon which is abundantly available in nature. The high tensile strength and low density of graphene is the added advantage as it is used as a reinforced material with Aluminium 6061.  Graphene was found to be a more suitable reinforcing material that improves tribological properties of metal. Composite materials are mixtures of various parent materials resulting in the formation of materials having a mix of varied desired properties like low weight, larger stiffness, higher specific strength etc. The composite materials so obtained invariably have superior properties to their parental ones. So these materials become a really enticing notice for higher strengthened material for industrial sector. This paper primarily focuses on distinctive effects of utilizing Graphene as reinforcement for Al-6061in the view of tribological characteristics. Graphene has outstanding mechanical and physical properties, creating it a perfect reinforcement material for lightweight weight and high strength metal matrix composites (MMC) like Al-6061. Fabrication, being a important step, because it controls the microstructure, that successively determines the properties of the material, was conducted by stir casting. Stir casting additionally helped within the dispersion of Graphene uniformly within the metal matrix composite. To analyze the effect of tribological parameters damage resistance of the metal matrix composite, linear reciprocating tribometer was used.

Aluminium based composite are getting a vast scope nowadays because of its properties and availability. In the present work, fly ash and AL2O3 reinforced composite are prepared using stir casting technique for varying wt.% (fly ash 3% and AL2O3 3%, 6% & 9%). Hardness and tensile properties were determined, with the addition of reinforcement the properties are improved compared to the parent metal alone. Based on the evaluation 6% AL2O3 and 3%fly ash gives a better result as compared to other composition.

Solid Glass Microspheres (SGM) in the range of 10–20 vol. % were used as reinforcement for making aluminium alloy metal matrix composite having density 2.66–2.68 gm/cc using stir-casting technique. Aluminium alloys are not new for synthesizing Metal Matrix Composites (MMC’s), as they have already established their exceptional ability to sketch out the material for required properties where high strength is expected from a low density material. This has made them one of the widely used materials for aeronautics and marine applications where strength and weight are among the major governing factors for the suitability of any material. So, an effort is made to enhance the strength of aluminium alloy LM13 without affecting its lightness, by reinforcing it with Solid Glass Microspheres (SGM). This synthesized composite, is characterized in terms of its density and compressive deformation behaviour. It was observed that the developed composite behaves somewhat like a high strength aluminium foam under compressive deformation as exhibited in the stress–strain curves. The results of density evaluation and compression showed a substantial enhancement in the compressive strength of the developed composite with a considerably low change in density.
