Abstract Scope |
The objective of this work is to analyze the microstructure and texture upon friction stir welding of AZ31 Mg and Al 6061 alloys. Various light-weighting applications prompt for welding of Mg alloys with another material. Friction stir welding has shown potential to join dissimilar materials, with limited formation of undesirable intermetallics. The joint performance is affected by the texture and microstructure, which evolve during the process owing to higher temperature plastic deformation. The friction stir welding of AZ31 Mg and Al 6061 is performed at 100 mm/min feed rate and 500 rpm tool rotation speed with 2° tilt angle. In the stir region, both materials have undergone grain refinement. However, the stir region itself is asymmetrical with respect to the tool centreline and higher grain refinement is observed on the AZ31 Mg side. Further, basal texture and shear texture are noticed on the AZ31 Mg and Al 6061 sides, respectively. |
