“…The nugget and the base metal both exhibit a strong {0 0 0 2} texture but with their basal plane aligned in orthogonal directions. This texture variation is consistent with Woo et al neutron diffraction experiment [12] and Yang et al X-ray diffraction experiment [7]. Regarding that the resulting c-axis in the base metal and in the nugget are orthogonal to the tensile loading direction, plastic deformation cannot be easily initiated in these regions.…”

“…Therefore, the grain size influence is not predominant on the mechanical behaviour. This does not confirm Yang et al recent study [7] which highlighted that increasing the shoulder size resulted in higher UTS and a fracture location moving from TMAZ to the nugget.…”

“…The local texture evolution was investigated using EBSD. A previous study [7] reported that the shoulder size did not influence the texture modification induced by FSW in the nugget but could weaken the {0 0 0 2} texture in the TMAZ so that fracture could occur in the nugget. The shoulder size did not induce such large modification in our study so that the fracture was still located in the TMAZ.…”

“…During FSW, the complex thermo-mechanical input results in the microstructure modification in the weld zone and the generation of distinct microstructural areas: the nugget, the thermo-mechanically affected zone (TMAZ), the heat affected zone (HAZ) and the base metal (BM) [2]. Previous studies were mainly focused on the influence of the welding parameters on the resulting tensile properties [5][6][7][8][9][10]. The microstructural evolution observed during FSW and the residual stresses involved will influence the mechanical properties of the welds [6][7][8][9][10][11][12].…”

Friction stir welds produced from magnesium alloy hot rolled plates were studied. Electron back scattered diffraction was used to determine the texture evolution, residual stresses were analysed using X ray diffraction and tensile tests coupled with speckle interferometry were performed. The residual stresses induced during friction stir welding present a major influence on the final mechanical properties.

Using magnesium alloys reduce the weight of a vehicle considerably, but the available fusion welding methods impose restrictions on the fabrication of magnesium alloy components. Friction stir welding is an efficient method to weld magnesium alloys, but due to extreme plasticization and stirring of materials, the microstructures are transformed. Similar to other alloys, friction stir welded magnesium alloys are also susceptible to corrosion. In the present work, dissimilar AZ31 and AZ91 Mg alloys were friction stir welded at varying welding conditions. The variable presence of small cracks with a high amount of oxide, and microstructural and textural differences result in varying joint strength, that is, joint efficiency, which has a maximum value of approximately 90% of a stronger base material. The maximum corrosion potential obtained in welded zones is approximately equal to a base material that conveys similar electrochemical behaviour. The minimum corrosion rate of 0.22 mm/year is observed in the sample welded at 700 rpm tool rotational speed, 30 mm/min welding speed and 18 mm shoulder diameter.
