Feasibility study of friction stir welding of 6061-T6 aluminium alloy with AISI 1018 steel
The present work demonstrates that friction stir welding (FSW) is a feasible route for joining 6061 aluminium (Al) alloy to AISI 1018 steel. The weld has a good weld quality and is free of cracks and porosity. The tensile failure happened at the boundary between the nugget and thermomechanically affected zone of the base Al alloy, indicating that the weld has a higher joining strength. Despite ...
متن کاملTwo-dimensional Mapping of Residual Strains in 6061-t6 Aluminum Alloy Friction Stir Welds
The residual strain profiles were measured through the thickness of friction-stir welded (FSW) plates using neutron diffraction to study the relationship between the angular distortion and the residual strain distribution. Three different weld specimens were prepared from a 6061-T6 aluminum alloy with the purpose of separating the effects of the frictional heat and plastic deformation on the re...

15 صفحه اولA study on the sub-structure and mechanical properties of friction stir processed AA 6061-T6 joints with ultra-fine grained structure
Ultra-fine grained (UFG) structure (~0.6 µm) was produced in the stir zone (SZ) of 6061-T6 aluminum alloy joints using friction stir processing (FSP) cooled by liquid nitrogen (N2). A new experimental set-up was used to simultaneously quench the lower and upper surfaces of the samples during the processing. In addition, FSPed joints, using a steel backing plate, were produced at room temperatur...
متن کاملAn alternative to increase the mechanical strength of 6061-T6 GMA weldments
Fusion welding of heat treatable aluminum alloys leads to a significant loss of strength in the heat affected zone (HAZ) due to overaging. This work was aimed to improve the mechanical properties of Al-6061 welds. Plates of 6 mm in thickness were solutionised at 530◦C for 1 h followed by water quenching and aging at 160◦C for times between 13 to 19 hours. Welding was performed with the gas meta...
