Abstract:

A device for measuring crystal orientation with an x-ray source using the Laue method and includes an apparatus for mapping a polycrystalline surface having a grain orientation. The apparatus including an x-ray source creating an x-ray beam, the beam having polychromatic photons, the beam collimated to a point on the polycrystalline surface. A two-dimensional x-ray detector with an aperture, the x-ray beam passing through the aperture, the detector detecting and collecting polychromatic photons diffracted from the polycrystalline surface and onto the detector. A means for moving the polycrystalline surface with respect to the x-ray source to collect a plurality of diffracted x-rays which define a Laue pattern. A data processing means to collect Laue patterns of the polycrystalline surface based upon the plurality of diffracted x-rays, the Laue patterns identifying a plurality of crystallographic orientations and a plurality of grain surface areas on the polycrystalline surface.
