![]() ![]() ![]() Friction stir welding experimentation and measurements show a decrease in the values of all measured mechanical properties compared to the original material. The second phase is oriented towards estimating the residual stresses by combining two pre-existing models of friction stir welding and burnishing developed by the same authors using ANSYS ®. The improvement of the topology and deep hardness distribution is measured and discussed, and the evolution of mechanical properties is assessed through tensile tests. Then, the welding line is deformed locally by ball burnishing. ![]() The first one is experimental and consists of welding aluminum AA2024-T3 plates while combining different tool rotations and welding speeds. The metallurgical and topological states of materials joined by this welding technique are typically detrimental to the ulterior performance of the workpiece, and it is believed that ball burnishing can improve these states to enhance functioning. This paper deals with the improvement of the material surface state of friction stir welding paths modified in situ by plastic deformation through ball burnishing. ![]()
