- Abstract:
-
High resolution, cross-correlation based, electron backscatter diffraction (EBSD) measures the variation of elastics trains and lattice rotations from a reference state. Regions near grain boundaries are often of interest but overlap of patterns from the two grains could reduce accuracy of the cross-correlation analysis. To explore this concern, patterns from the interior of two grains have been mixed to simulate the interaction volume crossing a grain boundary so that the effect on the accur...

- Data examining the spatial resolution of electron backscatter diffraction. EBSD patterns were obtained from a Zr alloy (zircaloy-4) using a Bruker eFlashHR detector at full 1600x1152 pixel resolution on an Zeiss Auriga SEM at 20keV and 10nA. Cross correlation analysis carried out within Matlab was used to measure the degree of pattern overlap and its effects on errors in strain measurements.

Access Document
Why is the content I wish to access not available via ORA?
Bibliographic data (the information relating to research outputs) and full-text items (e.g. articles, theses, reports, etc.) arrive in ORA from several different sources. Unfortunately we are not able to make available the full-text for every research output.
Please contact the ORA team (
