Aluminium Metal Matrix Composites reinforced with particulate silicon carbide and Boron Carbide reinforcements have demanding applications in aerospace and automotive domains. With a lack of sufficient literature on this composite combination and emerging demands, it is highly essential to understand their weldability and material characteristics. Friction Stir Welding is a feasible choice for joining of Aluminium Metal Matrix Composites over the conventional fusion welding owing to narrow Heat Affected Zone and minimized Intermetallic Compound formation at the weld interface. In this work, AA6061 matrix composite plates are fabricated with a varying weight percentage of particulate SiC and B4C reinforcements using powder metallurgy process. The study mainly focusses on the tensile strength, hardness and microstructural properties of composite plates joined using Friction Stir welding subjected to a constant load of 8KN at three-level process parameters experimental design of varying spindle speed, weld speed and plunge depth. The outcomes reveal sufficient information on the microstructural analysis of the weldments and the subsequent effects on the material strength. Followed by, statistical process parameter optimization is performed to improve the tensile properties of the weldments and the results are experimentally validated. The study confirms the feasibility and applicability of FSW in joining Al-MMCs.

Laser drilling of monolithic materials like metals and alloys is a well-established process and used extensively in a wide range of applications in many sectors including aerospace, medical and automotive. However, conventional laser drilling of materials like metal matrix composites is challenging due to the differences in the chemical and physical properties of the hard ceramic reinforcement particles and the soft-metal matrix. The water-jet guided laser process has the potential to machine advanced materials such as an aluminium metal matrix composite reinforced with silicon carbide particles (Al MMC), with exceptional quality. The main objective of this research is to understand the material removal mechanism associated with water-jet guided laser drilling of Al MMCs and compare this with conventional laser drilling of Al MMC. Experimental results showed that the water-jet guided laser process is an excellent technique for drilling holes in composite materials like metal matrix composites. During water-jet guided laser drilling of Al MMC, the material has been removed by cold ablation, without leaving any residual melt layer within the bulk material. Both soft-matrix and hard-particles are removed by the same process of cold ablation, which is completely different to the conventional laser drilling process in which the solid SiC are ejected without melting, along with the molten aluminium.
