Fig.4. Low (a, b) and locally high (c, d) magnified KAM distributions of the TC4 sample before (a, c) and after (b, d) pulsed magnetic treatment (The KAM distribution after treatment is more homogeneous than that before treatment totally. Positions 1, 2 and 3 in Figs.4a and b as an example indicate the variation of KAM near the grain boundaries. The boxes in Figs.4c and d forcefully indicate the reduction of KAM in the specific grain while the ellipses in Figs.4c and d indicate the increase of KAM in the specific grains. Positions 4, 5 and 6 in Figs.4c and d as an example indicate the variation of KAM and especially the variation of the shape of the grain boundaries)
