Electron Backscatter Diffraction (EBSD)
CrSi2
This material is made up of grains of two orientations separated by a boundary of 30° about [0001] (shown in yellow).
Pure Chromium after a single pass through Equal Channel Angle Extrusion.

PRIAS™ Orientation Contrast from a Duplex 2205 steel
Micro X-ray Fluorescence (Micro-XRF)
A sample acquired from the “table” of a cut natural ruby. The elements Ti, V, Cr, Fe and Ga are of particular interest in the analysis of natural rubies, as they can be used to identify the geological source of a ruby.
EDXRF measurement of ruby measured at reference orientation, 0 degrees. Diffraction peaks are denoted by asterisks
EDXRF measurement of ruby measured at 90 degrees
EDXRF measurement of ruby measured at 180 degrees
Recombination of EDXRF spectra at 0, 90 and 180 degrees which eliminates the interfering diffraction peaks in ruby measurement
