The paper presents the results of experimental investigation on the characterization and analysis of mechanical properties of composites formed. Three aluminum metal matrix composites reinforced with 10 wt% of B4C, SiC and Al2O3 particles were processed. The stir casting method followed by hot rolling was used for fabrications of aluminium 7075 metal matrix composites, being one of the cost effective industrial methods. Experimental results show nearly a uniform distribution and good dispersion of reinforced particles within aluminium matrix. Both tensile strength and hardness are enhanced by incorporation of reinforcement particles into the matrix. Scanning electron microscope (SEM) analysis was done to study the good dispersion of particles and surface characteristics.

Abstract: Aluminum based metal matrix composites (AMCs) are very useful and demanded in space and vehicle sector because they carry excellent properties like light weight, ductility, great strength, and toughness apart from this they can be handled by predictable methods. Melt casting and powder metallurgy methods are widely adopted for fabricating the compounds as compared to other technique. Casting methods is used for prepare the complex shapes because powder metallurgy technique is not able to prepare such type of complex shape though it is further cost effective than the melt casting techniques. Casting with stirring has certain advantages over powder metallurgy because it allows for better matrix particle adhesion, easier matrix structure control, low cost, simplicity, and the formation of precise shapes. The Casting process can be utilised with a wide range of materials. Aluminium metal matrix composites, on the other hand, have been found to have superior wear resistance and mechanical qualities. The tribological and mechanical properties of aluminium based alloy matrix composites manufactured using various casting processes are summarised in this review paper. Keywords: Metal Matrix based on aluminium, Manufacture methods, mechanical and tribological characterization.

The present paper describes a cost effective route to produce Al alloy-10 wt % TiB2 metal matrix composites by in-situ molten flux assisted reaction synthesis. Now a days main focus is given to aluminium alloy as a matrix material due to its unique combination of good corrosion resistance, low density, superior mechanical properties, good vibration damping, higher wear resistance due to which alloy finds extensive applications in naval applications. With TiB2 as particulate addition in Al-Alloy (Al-5Mg) matrix properties of alloy can greatly be improved.

AbstractPowder Metallurgy (P/M) is playing a vital role to synthesize variety of materials in the field of aerospace, automobile, ordnance, petroleum and petrochemical industries. P/M is an outstanding process to produce components with good mechanical and tribological properties such as strength, hardness, impact resistance and wear resistance. Recently metal matrix composites (MMC) replace conventional alloys because of their extraordinary characteristics. Currently Aluminium, Copper, Magnesium, Titanium and Iron have been used as matrix materials and materials like TiC, SiC, B4C, WC, Cr3C, TiO2, ZrO2, Gr, MoS2, and Si3N4 have been used as reinforcements to synthesize metal matrix composites. When compare P/M with other manufacturing methods, it offers ordered microstructure with improved physical, mechanical and tribological properties. From these, powder metallurgy could be commented as an extremely active and cost-effective method when compare with other process. This paper explains the selection suitable process parameters for synthesize MMCs using P/M technique. This paper made an attempt to present the mechanical and tribological properties of various composites fabricated through powder metallurgy technique.

Broad Program

As part of a broad program on composite materials, the role of the interface on the micromechanics of deformation of metal-matrix composites is being studied. The approach is to correlate elastic behavior, micro and macroyielding, flow, and fracture behavior with associated structural detail (dislocation substructure, fracture characteristics) and stress-state. This provides an understanding of the mode of deformation from an atomistic viewpoint; a critical evaluation can then be made of existing models of composite behavior based on continuum mechanics. This paper covers the electron microscopy (transmission, fractography, scanning microscopy) of two distinct forms of composite material: conventional fiber-reinforced (aluminum-stainless steel) and directionally solidified eutectic alloys (aluminum-copper). In the former, the interface is in the form of a compound and/or solid solution whereas in directionally solidified alloys, the interface consists of a precise crystallographic boundary between the two constituents of the eutectic.

Aluminum-based metal matrix composites offer unique combinations of high specific strength and high stiffness. The improvement in strength and stiffness is related to the particulate reinforcement and the particular matrix alloy chosen. In this way, the metal matrix composite can be tailored for specific materials applications. The microstructural characterization of metal matrix composites is thus important in the development of these materials. In this study, the structure of a p/m 2014-SiC particulate metal matrix composite has been examined after extrusion and tensile deformation.Thin-foil specimens of the 2014-20 vol.% SiCp metal matrix composite were prepared by dimpling to approximately 35 μm prior to ion-milling using a Gatan Dual Ion Mill equipped with a cold stage. These samples were then examined in a Philips 400T TEM/STEM operated at 120 kV. Two material conditions were evaluated: after extrusion (80:1); and after tensile deformation at 250°C.
