This study was conducted to investigate the synthesis, characterization and mechanical properties of aluminium reinforced with ferrotitanium and silicon carbide via stir casting technique. Microstructures of as-cast samples were analysed using optical and scanning electron microscopes equipped with energy-dispersive X-ray spectroscopy. The mechanical properties in terms of hardness, tensile, tribological behaviour and fracture were assessed. Results showed that the homogeneous dispersion of reinforcement was within the metal matrix composite. Tribological study revealed a decrease in frictional coefficient of the composites with lowest frictional coefficient observed in composite with addition of silicon carbide as reinforcement. Morphology of fractured surface displayed a reduction in the size of dimples formed in reinforced aluminium composites when compared with larger dimple sizes observed in as-cast aluminium alloy.

Al6063 Alloy

In this work, metal matrix composites were fabricated using the electromagnetic stir casting process by adding 5 and 10 wt% silicon carbide in Al6063 alloy. Hardness, ultimate tensile strength, and yield strength of the developed Al6063/SiC/5p metal matrix composites have been improved by 17%, 18%, and 37%, respectively, in comparison with Al6063 alloy. Further, an improvement of 25%, 37%, and 71% in hardness, ultimate tensile strength, and yield strength, respectively, have been noted for Al6063/SiC/10p metal matrix composite in comparison with the Al6063 alloy. Results revealed that the hardness and strength of metal matrix composites were increased with silicon carbide addition in Al6063 alloy. The presence of different elements in metal matrix composites was identified by energy-dispersive X-ray spectroscopy and X-ray diffraction techniques. Energy-dispersive X-ray spectroscopy was used for elemental mapping observation of the metal matrix composites. Uniform distribution of reinforcement particles in the matrix with improved mechanical properties of metal matrix composites proved the adequacy of the electromagnetic stir casting process. The presence of facets and dimples in fractographs indicated the mixed mode of fracture. The average percentage porosity presented in Al6063/silicon carbide/5p and Al6063/SiC/10p metal matrix composites was found to be 4.68% and 5.22%, respectively.

Metal matrix composites are the resultant of combination of two or more elements or compounds, possessing enhanced characteristics than the individual constituents present in them. This paper deals with the fabrication of Al 2014-SiC composite and investigation of its Microstructure and Mechanical properties. 2014 Aluminium alloy is characterized by good hardness. It is selected as the base metal. The Silicon Carbide is characterized by good strength and low density (3.21 g/cm3). It is chosen as the reinforcement. Silicon Carbide is coated with Nickel by electroless method to increase its wettability and binding properties. The fabrication of metal matrix composites is done by stir casting in a furnace, by introducing the required quantities of reinforcement into molten Aluminium alloy. The reinforcement and alloy is mixed by means of stirring, with the help of a stirrer. The base alloy and the composites are then tested for mechanical properties such as tensile strength, flexural strength, impact strength and hardness. The fabricated samples have higher tensile strength and impact strength than the alloy. Microstructure of the samples, are analyzed using optical microscope.

Nano technology has fascinated the attention of numerous material scientists and design engineers. The nano scaled particulates incorporation exhibit many attractive and special properties. The inclusion of nano particulates into the copper matrix might augments the hardness, ultimate tensile strength and yield strength significantly increases, maintaining the ductility. In this paper, the nano Al2O3 reinforced copper - 5%tin- metal matrix composites were manufactured by stir casting technique and reinforcement is varied from 0wt. % to 9wt. % in ventures of 3wt. %. The nano composites are characterized in terms of their mechanical and wear properties. Results revealed that, the distribution of nano Al2O3 particulates is fairly uniform in copper - 5%tin metal matrix. As the level of reinforcement increases, hardness, yield strength, ultimate tensile strength, and wear resistance of the copper - 5%tin – nano Al2O3 metal matrix composites increases. The developed nano metal matrix composites may be an alternative material for bearing applications

Hybrid Metal Matrix Composites

The aim of the present study is to investigate the effect of alumina (Al2O3)–carbon (C) reinforcement on the properties of aluminium matrix. Aluminium matrix reinforced with Al2O3–carbon (2.5, 5, 7.5 and 10 wt.%) in equal proportion was prepared by stir casting. Phase, microstructure, EDS, density, hardness, impact strength and tensile strength of prepared samples have been investigated. X-ray diffraction reports the intermediate phase formation between the matrix and reinforcement phase due to interfacial bonding between them. Scanning electron microscopy shows that Al matrix has uniform distribution of reinforcement particles, i.e. Al2O3 and carbon. Density decreases due to variation of reinforcement because ceramic reinforcement has low density. Hardness decreases due to variation of carbon since it has soft nature. Impact strength was found to increase with addition of reinforcement. Hybrid composite of Al and 5% Al2O3 + 5% carbon reinforcement has maximum engineering and true ultimate tensile strength. It is expected that the present hybrid metal matrix composites will be useful for fabricating stock screws.
