“…The FSP process, like the FSW process, utilizes the motion of the rotating non-consumable tool to modify the structure (Bharti, Ghetiya and Patel, 2021). Severe deformation along with increasing temperature during the FSP process leads to microstructural changes at the desired location (Kumar and Goyat, 2023). For low melting point materials such as aluminum and magnesium, cooling can prevent the growth of recrystallized grains and the dissolution of solidi cation deposits in and around the agitated area.…”

In this study, Al6061 aluminum sheets and carbon nanotubes with 0, 0.1, 0.5 and 1.5 volume percent were used to produce FGM materials using the friction-stir process and important parameters such as rotational speed, traverse speed and tool angle were investigated for the impact strength and microhardness of the produced composites. The process was carried out at rotational speeds of 950, 1225 and 1500 rpm, traverse speeds of 30, 37.5 and 45 mm/min and angles of 2, 3 and 4 degrees and the mechanical properties and microstructure of the composite material produced were investigated. In order to reduce costs, increase the accuracy of the experimental tests, determine the optimal conditions and also ensure the effectiveness of the parameters for the samples, the response surface design method was applied using Design Expert and Minitab software. In the impact test results, the fracture energy of the manufactured composite material is lower than that of the starting material, and as the rotational speed and tool angle increase, the fracture energy decreases, but as the traverse speed increases, the fracture energy increases. The results of the microhardness test show that the hardness of the produced composites decreases compared to the starting material. As the speed and angle of the tool increases, the hardness decreases, but as the traverse speed increases, the hardness of the composite material increases. The investigation of the effect of the percentage of carbon nanotubes on hardness showed that hardness also increases with increasing percentage of nanotubes.

Friction Stir Processing (FSP) has become a famous solid‐state technology for the fabrication of a wide range of aluminum alloy‐based composites that today find multiple applications across the various metal industries. Generation of revolving, ribbon, bulk, excessive or mass flash as it is generally termed has been a common problem in numerous FSP works. When confronted by this challenge, many researchers apply different experimental and numerical modeling approaches or strategies to reduce the mass flash to practically acceptable limits since it often leads to undesirable loss of material and is also an unwanted defect. This subject is deficiently reviewed, and it therefore becomes the thrust of this paper, to investigate the common trends in mass flash generation during FSP and its commonly employed reduction strategies. Mass flash is caused by high rotational speed at low travel speed and vice versa, flat shoulder, no and low tilt angles, high plunge depth, axial force, and travel force. Mass flash causes material loss, loss of volume fraction control target, material thinning, and leads to poor quality fabrications. Mass flash reduction strategies include the use of high tool tilt angles, concaved tool shoulder, proportional rotational speed and travel speed, and optimal plunge depth, axial force and travel speed as supported by both the experimental and numerical modeling studies.
