a–c Microstructural information of a region of interest tracked during in situ loading, a grain boundary map obtained by EBSD; b Schmid factor map; c Young’s modulus map with unit in GPa; d–g snapshots taken during in situ tensile loading and visible slip traces are indicated by black arrows, and tensile axis is horizontal; h a SE image of a region from the sample after tensioning to a strain of 1%, and slip traces along TBs are indicated by black arrows; i, j Statistics of 150 TBs which have developed slip traces (red solid circles) and have not developed slip traces (blue solid squares) in a sample after tensioned to a strain of 1%, i diagram of Schmid factor versus the differences in Young’s modulus across TBs; j diagram of Schmid factor versus the length of TBs.
