Rendering of the strain in crystals A and B for each reflection at 23°C and 587°C. In the top row of each quadrant the milled face is shown with a slice perpendicular to the x-axis. The bottom row of each quadrant is the 2D view of the corresponding slice. The small edge at the bottom of crystal B is a twin domain boundary marking a region of missing intensity. The black arrows represent the Bragg vector direction. The coordinate axes are positioned in sample space and plotted with a length of 250 nm. Numbered white arrows highlight trench-like structures that are reminiscent of dislocations. The blue hashed region at 587°C on the top face of the (200) reflection for crystal B is a reconstruction artefact (see Section 2.3[link]) and does not physically represent a compressive layer.
