Abstract In this study, the effect of naturally available and low-cost kaoline particles on the microstructural and mechanical behaviour of Al- SiC- Kaoline Hybrid metal matrix composite was investigated. Al-10% SiC- x% Kaoline (X = 0, 2, 4, 6, 8) composite samples were fabricated through powder metallurgy technique by applying a compaction pressure of 350 MPa. The fabricated composite samples were subjected to Density, Hardness, tensile and impact tests to study the mechanical behaviour of fabricated hybrid composite. The presence of SiC and Kaoline reinforcements was confirmed by using SEM and X-Ray Diffraction analysis. It was observed that the maximum ultimate tensile strength (U.T.S) and maximum Yield Strength (Y.S) of the hybrid composite were found to be 263 MPa and 202 MPa for Al-10%SiC-4%kaoline reinforcement. The formation of the intermetallic compound such as Al2Cu was observed in XRD and SEM analysis for Al-10% SiC-6 % kaoline and Al-10% SiC-8% of kaoline reinforcement which leads to decrease in the U.T.S and Y.S of fabricated specimens. The impact strength of Al-10%SiC-8% kaoline found to be decreased by 44.4% compared to unreinforced Aluminium due to the presence of harder SiC and Kaoline reinforcements particles. To study the fracture mechanism, Scanning Electron Microscopy study was carried on the fractured Tensile specimens which reveal that ductile fracture in unreinforced Al, Al-10% SiC, Al-10% SiC-2% Kaoline due to the formation of dimples and Brittle fracture was observed in Al-10% SiC-4% Kaoline, Al-10% SiC-6% Kaoline and Al-10% SiC-8% Kaoline due to the existence of cleavages and microcracks.

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.

Abstract This paper interprets the effect of sintering parameters like sintering time and sintering temperature as well as various sintering methods on distinct properties of the material. The variation of Physical, mechanical, and Tribological behaviour depending on sintering temperature, time and method based on various aluminium metal matrix composites have been investigated. The advantages of aluminium metal matrix composites are high strength to weight ratio, high wear resistance, and erosion resistance, etc. Aluminium Metal matrix composites have vast applications in various fields like structural, automobile, and aviation industries. The optimum value of sintering parameters and choice of sintering methods has a major role in getting these required properties of aluminium metal matrix composites prepared by the powder metallurgy process.
