A review on recent development in aluminium-copper friction stir welding Viresh Payak, Jawahar Paulraj, Barnik Saha Roy, Manish Bhargava, Pritam Das Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2024 Aluminium (Al) and copper (Cu) are widely employed in the industry due to their significant corrosion resistance and electrical conductive properties. The simultaneous requirement of different special properties has increased the trend of joining of Al and Cu. The joining of dissimilar materials has arisen as a new challenge in the research field in the past decade. Friction stir welding (FSW) is a very worthy process to join metals that aren't the same. This article delves into the intricacies of FSW to join compatible metals such as Al and Cu. The various parameters of FSW, namely tool design, tool pin offset, rotation speed, welding speed, tilt angle, and different types of welding joints, are highlighted in this article. It also goes through the different types of defects, microstructures, and intermetallic compounds (IMCs) that are formed during Al-Cu FSW. The electrical behavior and corrosion behavior of the weld zone in Al-Cu FSWed joints were also reviewed. Role of interlayer in some emphasis was also given to form effective joints.
A critical review of different properties of natural fibre-reinforced composites Ankit Samal, Sanjeev Kumar, Prasanna Kumar S Mural, Manish Bhargava, Sankar Narayan Das, Jitendra Kumar Katiyar Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2023 The eco-friendly and sustainable nature of bio-based fibres has received much interest from analysts to incorporate them into the polymer matrix. The research of filled plastic composites has sparked much attention in the recent decade as a way to address the lack of petroleum resources. The use of plastic has been prominent in almost everything, from ordinary things to complicated structures and industrial parts. Natural fibres entice researchers and scientists want to use their qualities by reinforcing them with polymers. Fibre loading percentage, size and orientation of fibres, stacking sequences, degree of interfacial adhesion, fibre surface treatments, hybridization, and integration of fillers and coupling agents all influence the qualities of natural fibre-reinforced polymer composites. The article summarizes different chemical remedies affecting natural fibres to enhance their qualities. Effects on water absorption and tribological behaviour caused by chemical therapies were included in this study. As a result, the natural fibre-reinforced composites’ mechanical characteristics have also been discussed in the present study.
Effects of SiC and carbon black on mechanical properties (tensile and flexural) of AA6082/SiC/CB metal matrix composites Manish Bhargava, Jawahar Paulraj International Journal of Materials and Product Technology, 2022 The metal matrix composites (MMCs) consisting aluminium as matrix with variety of high strength reinforcements are extensively used in the manufacturing sectors due to its excellent mechanical properties, i.e., high strength and stiffness to weight ratio and corrosion resistance. The objective of the current research work is to investigate the effect of infusion of silicon carbide (SiC) and carbon black on mechanical properties of aluminium 6082/SiC/carbon black MMCs. The experimental research shows that the mechanical properties initially increases with increase in weight fraction of SiC particulates and weight fraction of carbon black in the matrix. Further infusion of SiC and carbon black particulates in the matrix material decreases the mechanical properties of the composite. On the other hand, for tensile strength and flexural strength, the influence of SiC has been found most significant than carbon black while for impact strength and hardness, carbon black influence is more significant than SiC.
