“…The mechanical properties of these materials have continuous changes in the thickness of the material depending on the type of composition, and due to the continuity and gradualness of the composition of the constituent materials, they have effective mechanical properties compared to layered composite materials (Sai Charan et al, 2022). Due to the low heat transfer coe cient and high temperature resistance, ceramics can withstand very high temperatures and the metallic structure of the material causes the exibility of the fabricated composite, in other words, the integration and interruption of ceramic and metal with continuous changes from one surface to another in an instrument that can be easily fabricated, and due to the continuous and gradual changes in mechanical properties, the problems of discontinuity that exist in composite structures do not occur in the case of FGM (Merdaci et al, 2022). There are different methods to produce FGMs, and the appropriate method, FSP, was chosen (Sai, 2021).…”

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.
