“…The results have shown that the increase in the loading content of hBN up to 1.5 wt% has improved the ultimate tensile and wear properties of MMC but a higher reinforcement ratio led to a decrease in the MMC performance due to bigger agglomerations around the grain boundaries. 42 The results have also shown improvement in the hardness of MMC with the refinement of alloy grains.…”

Conventional manufacturing processes such as casting, forming, welding, machining, etc., have been optimized using different improvement techniques in the last few decades. The alterations in these processes have led to more efficient and productive manufacturing practices for the industry. One of these modification techniques is the deployment of ultrasonic vibrations in conventional manufacturing processes. In the last few decades, ultrasonic vibration assistance to manufacturing processes has seen an uprise and was the point of attraction for different research groups. Several improvements by utilizing ultrasonic vibration in manufacturing practices have been reported by the authors in the past. In this article, an attempt has been made to review all the reported techniques for different conventional processes viz. casting, forming, machining, and welding. The article outlines different research findings from the extensive work on ultrasonic vibration assistance showcasing the improved mechanical and morphological properties. The improvisation in the performance parameters viz. friction reduction, stress reduction, tool wear, surface finish, and grain structure has been witnessed by ultrasonic assistance in contrast to simple manufacturing processes. The outcomes have been summarized along with the optimized set of parameters from various studies.

“…The particulate reinforcements may have an effect contributing to the final results obtained. Table 4 in the ultrasonic welding process, there is a high frictional force generated by the sonotrode tip, due to the presence of dry friction, at the interface of welding of the two metals joining, which is tangential to the surface of the workpiece, is experiencing a rapid increase in temperature over its surface (Xu et al, 2005;Harichandran and Selvakumar, 2016;Chaubey et al, 2020;Madhukar et al, 2020). Furthermore, if the force is not sufficient during the operation, it may not transfer the ultrasonic oscillations that are supposed to generate the heat of fusion using the frictional motion of the sonotrode tip.…”

Aluminum metal matrix composites are a new class of materials that have gathered more attention from many materialists. Especially, the automotive components like a piston, cylinder block, brake drum, etc., fabricated by different reinforcement, which has exposed better performance over conventional engineering materials. Aluminum composites are generally fabricated by stir casting technique due to simplicity in operation and adaptive to mass or job order production. The paper provides a background for the readers interested in the production of metal matrix composites through stir casting. Based on the literature assessment, the special attentions taken by the researchers to enhance the uniform distribution of particle to avoid agglomeration are discussed. The composite performances mainly depend on the aluminum matrix, particle size, the quantity of reinforcement, preheating temperature of reinforcement, and processing parameters such as stirring speed, stirring time, and wetting agents. The selection of two reinforcements and their suitable parameters for wetting are attaining interest by many researchers and maybe opted as future scope.
