Fig. 4: Strain localisation associated with TBs: Three TBs in two regions are presented to illustrate the strain localisation along TBs, misorientation gradient and volumes with high strain at grain boundaries.

a, d Effective shear strain maps obtained by high resolution digital image correlation (HRDIC), where the four {111} plane traces are presented and the ones parallel to the TBs are coloured in red with their Schmid factors noted, and the colour scale of strain maps is presented below (d); b, e Kernel Average Misorientation (KAM) maps, and the colour scale of misorientations is presented below (e); c, f backscattered electron (BSE) images.
