(a) Specimen 1 EBSD GB maps identifying the SGB (in red) extracted for analysis (location of extraction highlighted in yellow). (b-c) Specimen 1 SGB SEM images of the FIB preparation of the APT tip. (d) Specimen 1 SGB 3D atom-by-atom LEAP tomography reconstruction showing the cylindrical ROI for analysis (ions shown are Si only; 100% of ions are shown). (e) Specimen 1 EBSD GB maps identifying the RGB (in blue) extracted for analysis (location of extraction highlighted in yellow). (f-g) Specimen 1 RGB SEM images of the FIB preparation of the APT tip. (h) Specimen 1 RGB 3D atom-by-atom LEAP tomography reconstruction showing the cylindrical ROI for analysis (ions shown are Si only; 100% of ions are shown).
