Fig. 6.. The magnified image of the white box in Fig. 5(g) shows the reaction of the dislocation configuration. The dislocation pairs in the white box are approaching to annihilate. The red and yellow arrows indicate the direction of the dislocation movement. Annihilation of a yellow dislocation and a green dislocation occurs inside the white circle. The strain is: (a) 0.0504; (b) 0.0514; (c) 0.0540; (d) 0.0556; (e) 0.0633; (f) 0.0648.
