Examples of OIM work by the use of GrainSweeper. In both cases, orientations are mapped on a colour scale. Black voxels indicate voxels with no orientation assignment. (Left) Reconstruction based on three-dimensional detector data of a layer within an NaCl single crystal with a prehistory of 16.5% compression following by annealing. Subgrains are visible. Courtesy of S. Schmidt. (Right) Reconstruction of a layer within a 30% cold-rolled Al1050 sample using only a far-field detector. The white and black lines denote misorientations of 2 and 15°, respectively. Three grains are identified and marked as A, B and C. Superposed on the OIM map are four red dots (numbered 2, 4, 5 and 6) marking the positions of nuclei appearing during the subsequent annealing. The longer dimension of the cross section is 1 mm.
