a Low-magnification SEM backscatter image, b corresponding EBSD IPF map and c corresponding EBSD phase maps showing FCC grains and fine scale BCC/B2 precipitates at the grain boundaries, from the same region. d Higher-magnification SEM backscatter image showing dark contrast BCC/B2 precipitates at the FCC grain boundaries and triple junctions, as well as nanometer-scale precipitates within the grains e corresponding EBSD IPF maps from the same region, and f corresponding EBSD phase map showing only the FCC grains and BCC/B2 precipitates. Note that the additional fine-scale intragranular precipitates are indexed as FCC and the BCC phase is represented in blue, and the FCC phase is in red. Source data are provided as a Source Data file.
