X-ray evaluation method with electron diffraction photos for orientation determination

摘要

The method involves evaluating X-ray and electron diffraction photos, for orientation and precision determination of alloy composition. This enables determining the grating distortions and spatial state of stress. A computer technology method is used for comparing a diffraction photograph of a section from the reflection system is compare with one or a series of computer simulations, using a position-shape identification program. For the orientation determination, the position and shape identification program is used to turn and move the digitalised diffraction photograph until a maximum correspondence to the computer simulations of the diffraction reflections, or stereogram, is attained.
