This data was recorded by Herb Miller, while at CMU, in 2003. A sintered disk of spinel, obtained from RCS technologies, was annealed in air at 1600°C for 48 hours. After this treatment, the average grain size was 12 micons. Crystal orientation maps on a planar section were obtained using an EBSD mapping system (TexSEM Laboratories, Inc.) integrated with a scanning electron microscope (Phillips XL40 FEG). Sixteen maps were obtained, each with an area of 400 microns x 400 microns. Within each map, orientations were recorded at an interval of 2 microns. When combined, these maps contained ~8500 grains.The complete analysis of the data can be found in the following publication:
