WebThe percentage of high-angle grain boundaries (HAGBs) with misorientations above 15° was below 50%. This result is clearly confirmed in Figure 4d–f showing OIMs taken from a much smaller area, i.e., with a higher resolution. These figures show that low-angle boundaries (LAGBs; marked in red) are more frequent than HAGBs (marked in blue).
