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.

Abstract The paper constitutes the culmination of the foregoing investigations concerning the influence of short carbon fibre on the enhancement of AlMg10 alloy properties. The presented work brings forward the results of examinations of mechanical and tribological properties of metal matrix composites (MMCs) based on this alloy. Composites were produced by two methods: either by gravity casting or by squeeze casting in semi-solid state of a composite suspension previously obtained through mixing of its components. The volume fraction of the reinforcing phase varied and took the value of 5, or 10, or finally 15 vol. %. Specimens cut out of the experimental castings were examined with respect both to their mechanical properties, i.e. the tensile strength and unit elongation, and to their tribological behaviour. A series of examinations of the mechanical properties proved a slight increase in tensile strength and a minor decrease in unit elongation of the examined composite materials both for gravity cast and squeeze cast specimens, as compared with the properties of pure matrix alloy. The introduction of short carbon fibre into the matrix alloy resulted also in the increased abrasive wear resistance of the examined composites in comparison to the non-reinforced matrix.

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.
