Orientation and strain maps for the Al gasket surrounding a sample similar to WG102. (a) IPF color maps of pixel orientation relative to the z and x axes in the sample reference frame. (b) Pixel orientation (lower hemisphere) for a selection of Miller indices. (c) Strain maps computed for several {hkl} diffraction rings. d is the d spacing for crystal planes, and
d0 corresponds to the median d spacing for all diffraction peaks belonging to the selected {hkl} family over the whole sample. Strain is given in engineering convention (negative strain for shortening) and is expressed in a direction orthogonal to the orientation of the selected {hkl} crystal planes. |
