a Correlation index map with overlaid monoclinic oxide grain boundaries shown in black (interphase boundaries shown in green). The orientation of the Zr hcp unit cell is shown. The oxide growth direction is marked with an arrow. b Phase map with phase reliability values less than 10 shown as non-indexed points (in black) and indexed coloured according to the legend below (b). c Monoclinic ZrO2 orientation map coloured according to degrees away from the \(\{11\bar{2}\}\) pole according to colour legend in d. d Normalised frequency of orientations and pole figure with respect to degrees away from the main texture component \({\{11\bar{2}\}}_{{{{{{\bf{m}}}}}}-{{{{{\bf{Z}}}}}}{{{{{\bf{r}}}}}}{{{{{{\bf{O}}}}}}}_{2}}\)for both EBSD and SPED data. Denoted with orange disks and red crosses are the major and minor theoretical orientation \(\{11\bar{2}\} < 111{ > }_{{{{{{\bf{m}}}}}}-{{{{{\bf{Z}}}}}}{{{{{\bf{r}}}}}}{{{{{{\bf{O}}}}}}}_{2}}||\{0002\} < 1\bar{1}00{ > }_{{{{{{\bf{Z}}}}}}{{{{{\bf{r}}}}}}}\) and \(\{31\bar{2}\} < 111{ > }_{{{{{{\bf{m}}}}}}-{{{{{\bf{Z}}}}}}{{{{{\bf{r}}}}}}{{{{{{\bf{O}}}}}}}_{2}}||\{0002\} < 1\bar{1}00{ > }_{{{{{{\bf{Z}}}}}}{{{{{\bf{r}}}}}}}\).
