Figure 4. Plastic deformation of matrix and freckle grains. (A) Statistics on the KAM variation with MA in four brands of alloys. The orange curve is used to describe the trend. (B) BF-STEM images of the matrix. (C) BF-STEM images of the freckle grain. Dislocations are marked with yellow arrows. (D) High magnification HAADF-STEM image of the dislocation core, corresponding to the red square in image (C). Burgers vectors are determined by the Burgers circuit.
