This paper presents the development and characterization of aluminium alloy 6063 based metal matrix composite with varying combinations of fly ash and Borosilicate reinforcements.  In the present work, the aluminium alloy 6063 (AA) is taken at a constant 84 vol% while the reinforcements Fly Ash (FA) and Borosilicate (B) are varied in the proportions of 2%, 4% 8%, 125 and 14%. Six samples were fabricated by stir casting and the mechanical properties were analyzed using tensile test, hardness test and wear test while the microstructure is analyzed by obtaining SEM and EDX images of the specimen. It is seen that both the reinforcements used in this study, increased the tensile and wear resistance of the alloy. The desirable mechanical and micro structural properties were found to be in the specimen with 84% AA, 14% FA and 2% B. The tensile strength of the aluminum alloy at this desirable combination is found to increase by 11.97%, ductility by 36.75% and the wear resistance by 62%.  This metal matrix composite of AA6063 with fly ash and Borosilicate reinforcements can be used in automobile, aerospace and structural applications where wear resistance and tensile properties are mainly required.

Metal Matrix Composite Material

For the past few decades the wheels of an automobile are usually made out of alloy materials. Due to the increased demand for peculiarity and enhanced outlook, metal matrix composites can be used for the alloy wheels. They enhance the performance of the vehicle by reducing its weight and thereby increasing its fuel efficiency. Many literature works are initiated and progressed on design and development of automotive alloy wheels. There is a scope for enhancing their properties with reinforcements. This study focuses on manufacturing a novel metal matrix composite material comprising aluminium as metal matrix and magnesium, silicon carbide and fly ash as reinforcements. The newly fabricated composition is tested. The alloy wheel is further analysed using ANSYS. The analysis results are compared with that of the existing aluminium alloy. The obtained results confirm that the proposed metal matrix composite is a reliable replacement for the aluminium alloy.

Al/TiB2 metal matrix composite (MMCs) was fabricated on aluminium AA1200 with the aim of improving the wear resistance property of the substrate. The characterization of the MMCs was carried out by Optical Microscopy (OM), Scanning Electron Microscopy (SEM/EDS) and X-ray Diffraction (XRD). The microhardness and wear resistance tests were achieved. Results showed that the microhardness property of the AA1200 was increased by three times the original value and the wear resistance was also significantly improved.
