“…This welding method was applied on aluminum materials thinner than 1 mm and thicker than 35 mm and it was found that very good mechanical properties were achieved. [27][28][29][30][31] The parameters used in the tests are given in Table 1. During the construction stage of friction-stir welding, the values of the movement rate and rotational speed were determined separately for different stirrer pins.…”

“…The friction-stir welding was started with ungrooved stirrer pins and the welding was performed with square, circular, saw-type, trapezoidal and triangular screwed 30,31 stirrer pins. In the welding operations involving the circular, trapezoidal and triangular screwed 3-groove pins, the components were welded at a rotational speed of 1200 r/min and a movement rate of 28 mm/min.…”

In this study, 20 different pins that could be employed in friction-stir welding were manufactured. These pins and the Al7075 T6 material were joined with the friction-stir-welding technique. Tensile tests, microstructure and microhardness measurements, scanning-electron-microscopy (SEM) and energy-dispersion-spectrometry (EDS) analyses were conducted on the components joint by friction-stir welding. Designs of the weld and the tip that achieve the best performance were determined.

“…Some of these factors could be mentioned as the physical and mechanical properties of the workpiece, the chemical composite, the tool material and tool geometry, the surface quality and rigidity, the kinematics of the cooling and lubrication equipment, the heat transfer property and liquidity, and the characteristics of the processing or shaping process [1][2][3][4]. The purpose of the burnishing process can be explained as the improvement of the surface roughness [5][6][7][8][9][10], wear, corrosion [11][12][13], fatigue resistance and tensile strength [11,12,14], and the microhardness [15][16][17] values of the workpiece as well as attaining dimensional precision. This processing method is preferred because of its high productivity in mass production compared to the grinding process.…”

5083 Al-Mg is the widely used material in food, chemistry, vehicle, machinery, and construction sectors, as well as in the aviation and space industries. The burnishing is normally used as the finishing operation for this material with the advantages such as surface roughness, reduced fracture formation, hardness, fatigue strength, and an increase of the wear resistance. These positive improvements are dependent on burnishing process parameters such as feed rate, burnishing force, ball diameter, and a number of revolutions. The study contains determination and optimization of the machining parameters and their effects on the surface roughness, microhardness, and the strength of 5083 Al-Mg material in the ball burnishing processes. Multiple regression and ANOVA analysis were performed to identify significant process parameters. A new Artificial Neural Networks (ANN) model with different neuron structures and algorithms has also been developed using experimental results to supplement the multiple regression model as the desired R 2 values could not be achieved with the latter. The ANOVA analysis indicated that both the burnishing force and the number of revolutions have a significant effect on the surface roughness and hardness with optimums 300 N and 200 rpm, respectively. Results from the two models were compared with each other. The developed ANN model is shown to estimate the surface roughness and the surface hardness with high reliability (R 2 = 0.999992) without costly experimental trials.

“…Authors designed the in situ rolling friction stir welding (IRFSW) process. Few works were found in the bibliography related to the application of burnishing techniques in FSW welded components [10,11]. For this reason, this work presents a series of tests carried out on a 2050 aluminum alloy in order to determine alternatives for stable hardness values in the area close to the welding.…”

Ball-burnishing is presented herein as a mechanical surface treatment for improving mechanical properties after the friction stir welding process. Ball-burnishing provides good surface finish, high compressive residual stresses, and a hardness increase of the surface layer. These characteristics are key for the fatigue life improvement of the component, and for wear resistance due to the higher hardness. This work presents a complete analysis of surface and sub-surface hardness values focusing on the determination of each process parameter influence. Burnishing pressure, radial width, and burnishing direction influence were analyzed. The tested material was 2050 aluminum alloy with two different heat treatments (T3 and T8). The optimum parameters were established, and a complete analysis of the surface hardness was performed. Results show that burnishing is an economical and feasible mechanical treatment for the quality improvement of component surfaces.
