Post irradiation crystal structure analysis. Phase mapping and strain calculation via PED. (a) Bright-field CTEM image after ion irradiation of 10 dpa from the ROI. (b) PED phase map from the region shown in (a) with HCP and FCC phases being marked in red and green, respectively. (c) Average normal strain (Max [εxx, εyy]) and shear strain (εxy) plotted for the HCP and FCC phases. Inset shows the representative PED patterns from FCC and HCP phases used to calculate strain and are outlined with green and red colors, respectively. Due to the resolution of PED technique for strain calculation, standard error bars are smaller than the symbol size used.
