Second thermal treatment. (a) Applied generator voltage V(t) and spatially averaged temperature T(t) within the XWBT FOV. (b) Enlarged view of the time interval with sustained dislocation activity. (c, d) Initial and final in situ XWBT images of dislocation evolution, recorded at t = 378 s and t = 650 s. (e) Intermediate snapshots taken in ROI-2 around indents H1, J1 and I1, illustrating dislocation evolution. Magenta and red arrows mark newly nucleated dislocations visible in the 220 reflection, while white dashed arrows denote the glide directions and black dashed arrows indicate segments that reached the opposite surface and slipped out of the crystal.
