First thermal treatment. (a) Applied generator voltage V(t) (blue) and spatially averaged temperature T(t) (red) within the XWBT FOV (green rectangle in Fig. 7[link]). (b) Enlarged view of the time interval in which dislocation motion occurred. (c, d) First and final in situ XWBT images of the full FOV recorded at t = 737 s and t = 818 s. (e) Intermediate ROI-1 snapshots around indent J1, illustrating dislocation evolution. Magenta arrows mark newly nucleated dislocations visible in the 220 reflection; purple arrows indicate extinct contrast; white dashed arrows denote glide directions.
