The definitive implementation of Aluminium alloys as the main choice for lighter structural components needs availability innovative manufacturing processes capable overcoming their poor formability at room temperature. local modifications material properties (by means short-term heat treatments) have shown effectiveness in such terms. In a previous study from same authors, it was experimentall...

Welding parameters for pipe joint friction stir welding (FSW) have been identified based on L-9 orthogonal arrays used in the Taguchi Method. Different parameters, such as rotation speed, travel speed and axial force, to produce several quality welded AA6063 butt joints. The reliability of products obtained FSW process can be improved through identification optimum combination parameters. Weld ...

The basic aim of present study is to examine the effect of main friction stir welding (FSW) parameters on the quality of AA 6063 plate welds. Welding of AA6063 was carried out by a vertical milling machine, using different tools with a stationary shoulder and during the welding no external heating system was used. Different welding parameters studied were the tool rotational speed which varied ...

In this study, the effects of heat treatment of aluminum alloy on the tube bending process were investigated in the rotary draw bending process. As two experimental and numerical simulation methods were used to determine the wall-thinning, ovality, and spring back for extruded, annealed, and aged AA6063 aluminum alloy tubes in different bending angles and bend radii. Numerical simulations were ...

In this paper, the loading path was optimized in hot metal gas forming (HMGF) process for making AA6063 cylindrical stepped tubes. For purpose, response surface method (RSM) and finite element (FEM) were applied using Design-Expert ABAQUS softwares, respectively. The parameters of internal pressure, pressure rate, axial feeding, punch speed examined based on central-composite design three level...
