Abstract
Aluminum 7075 is used in high-tech industries such as aircraft fuselages and wings. In this paper, the effect of friction stir process parameters on the mechanical properties of 7075 aluminum has been experimentally and statistically investigated. In order to reduce the number of experiments, Taguchi method was used among the different experimental design methods. Signal-to-noise ratio and analysis of variance methods were used to analyze the results of the experimental experiments. Rotational speed, traverse speed, tool shape, and number of process passes were considered as input parameters. Mechanical properties of 7075 aluminum, including hardness, strength, and elastic modulus, were also discussed and investigated as output parameters of the experimental experiments. According to the results obtained, friction stir process parameters are effective on the amount of plastic deformation and input temperature. Increasing traverse speed and decreasing rotational speed leads to a decrease in input temperature. Reducing temperature in friction stir process prevents grain size growth. With increasing grain size, mechanical properties such as hardness are reduced. The traverse speed is the most effective parameter on the hardness of 7075 aluminum with an effect of 55.22%. In addition to the positive effect on increasing hardness, increasing the traverse speed also leads to improved strength. The reduction in rotational speed and subsequent reduction in inlet temperature are the reasons for the increase in mechanical properties of 7075 series aluminum. Traverse speed and rotational speed have the highest and lowest effects on strength with 32.75 and 9.89 percent, respectively.
