In the original publication [1], there was a mistake in Figure 10d as published. The ultrafine-grained microstructure (Figure 10d) was shown for the wrong sample (same grade of AA6082-T6 aluminium, different thickness, under different welding parameters). This was caused by an incorrect image being included in the assembly of images (from Figure 3b in our paper [2], which is not in error).
We have gone back to the sample, repolished, re-etched, and retaken the image. Hence, the following correction needs to be made to Figure 10. The corrected Figure 10d appears below.
In the original publication, there was a mistake in Figure 3 as published. Figure 3 shows a photomontage of micrographs for the microstructures of the BFSW weld structure. These were shown for the wrong sample (same grade of AA6082-T6 aluminium, different thickness, under different welding parameters). This was caused by some incorrect images being included in the photomontage procedure (from Figure 4 in our paper [3], which is not in error).
We have gone back to the sample, repolished, re-etched, and retaken the images. Hence, the following correction needs to be made to Figure 3. The corrected Figure 3 appears below.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
