a Enlarged TEM image of the boxed region in Fig. 3 (ε = 5.3). The black arrow indicates the stretching direction. b Colour map of local εmax in the TEM image of (a) estimated by tracking the displacements of characteristic points from ε = 0.8–5.3. These local strain distributions do not fully reflect the history of the local strains from ε = 0. The tensile strain for ε = 0.8–5.3 is 2.5, as indicated on the colour bar. c Spatial distribution of normal stress in the stretching direction estimated by the finite element method (FEM) simulation. d–f Locations of crystallites identified from the intensities of the 200 spots (indicated by pink dots). (d–f) correspond to (a–c), respectively. Colour bars for (b, e) and (c, f) are displayed at the bottom.
