Fig. 4

a STEM composite micrograph showing the dislocation structures observed in the soft/hard grain pair when the soft grain is tilted to beam direction \(\left[ {2\overline {11} 0} \right]\) of the sample, under Loading Type Y. The TKD in the inset shows the analysed grain pair orientation with respect to the loading direction and b BF-TEM in two-beam condition showing a basal dislocation network in soft grain.
