Fig. 5.. The evolution of the movement and interaction of the ATGB dislocations in the sample under biaxial strain. The direction of the yellow arrow in the figure indicates the direction of the slip of the dislocation pair; The white box area highlights the interaction of the edge dislocation pairs; The green band region “gap” indicates the deformed grain region; The yellow band region indicates the torsion region where the dislocations interact, i.e., the torsion zone. The strains for the figure are: (a) 0; (b) 0.0144; (c) 0.0316; (d) 0.0381; (e) 0.0432; (f) 0.0453; (g) 0.0497; (h) 0.0504; (i) 0.0533; (j) 0.0612; (k) 0.0633; (l) 0.0648; (m) 0.0684; (n) 0.0782; (o) 0.1008; (p) 0.1105; (q) 0.1152; (r) 0.1202; (s) 0.1235; (t) 0.1256; (u) 0.1307; (v) 0.1353.
