Figure 7
The first part of the image displays a histogram graph presenting the misorientation angle on the x-axis, ranging from zero to sixty degrees, and the number fraction on the y-axis, ranging from zero to approximately zero point eight four. Six datasets, labelled HT-1150 °C, HT-870 °C, HT-650 °C, HT-425 °C, and As-built, show the distributions of misorientation angle for different heat treatments. The second part of the image contains two colour-coded microstructural images, labelled (b) and (c). Image (b) displays diverse microstructural features in a random pattern, while image (c) includes a label “BD” indicating a boundary, with both images showing colours that represent different structural regions from minimum to maximum values, as referenced in the accompanying legend. The scale bar indicates a length of seven hundred micrometres.(a) The misorientation angle distribution for different heat treatment routines, (b) the KAM maps corresponding to the heat-treated samples at 425°C and (c) 1,150°C. Here, Kernel maps were calculated concerning all neighbours at 500 nm distance, excluding values above 5°
