EBSD data (with patterns) for indexing of contrast inverted patterns
<p>Data needed to reproduce results from paper:</p> <p>Grzegorz Cios, Aimo Winkelmann, Gert Nolze, Tomasz Tokarski, Benedykt R. Jany, Piotr Bała,<br>EBSD and TKD analyses using inverted contrast Kikuchi diffraction patterns and alternative measurement geometries,<br>Ultramicroscopy, 2024, 114055, ISSN 0304-3991,<br>https://doi.org/10.1016/j.ultramic.2024.114055.<br>(https://www.sciencedirect.com/science/article/pii/S0304399124001347)</p> <p><br>Abstract: Electron backscatter diffraction (EBSD) patterns can exhibit Kikuchi bands with inverted contrast due to anomalous absorption. This can be observed, for example, on samples with nanoscale topography, in case of a low tilt backscattering geometry, or for transmission Kikuchi diffraction (TKD) on thicker samples. Three examples are discussed where contrast-inverted physics-based simulated master patterns have been applied to find the correct crystal orientation. As first EBSD example, self-assembled gold nanostructures made of Au fcc and Au hcp phases on single-crystal germanium were investigated. Gold covered about 12% of the mapped area, with only two thirds being successfully interpreted using standard Hough-based indexing. The remaining third was solved by brute force indexing using a contrast-inverted master pattern. The second EBSD example deals with maps collected at a non-tilted surface instead of the commonly used 70° tilted one. As TKD example, a jet-polished foil made of duplex stainless steel 2205 was examined. The thin part close to the hole edge producing normal-contrast patterns were standard indexed. The areas of the foil that become thicker with increasing distance from the edge of the hole produce contrast-inverted patterns. They covered three times the evaluable area and were successfully processed using the contrast-inverted master pattern. In the last example, inverted patterns collected at a non-tiled sample were mathematically inverted to normal contrast, and Hough/Radon-based indexing was successfully applied.<br>Keywords: EBSD; TKD; Contrast inversion; Topography; Kikuchi diffraction</p>
Deformed Iron EBSD data set
<p>Data from Electron Backscatter Diffraction analysis for a small (83 x 110) point map captured using a Bruker eFlash HR (1st generation) with full pattern resolution on a FEI Quanta instrument. The orientation data can be loaded using MTEX 5.0.3 (<a href="http://mtex-toolbox.github.io/">http://mtex-toolbox.github.io/</a>). The data is released to facilitate the development of new EBSD analysis methodologies, including AstroEBSD (<a href="https://github.com/benjaminbritton/AstroEBSD/">https://github.com/benjaminbritton/AstroEBSD/</a>) which has been developed by the Experimental Micromechanics Research Group (<a href="http://www.expmicromech.com">http://www.expmicromech.com</a>) & the Oxford Micromechanics group (<a href="http://users.ox.ac.uk/~ajw/">http://users.ox.ac.uk/~ajw/</a>). The data is from a lightly deformed sample of interstitial free steel (Ferrite). Orientation analysis was performed using eSprit 2.1 and this is contained within the h5 file. Figures from this data set are provided to illustrate the correct representation of the data. The x axis points right to left, the y axis points top to bottom, and the z axis is out of the page (as per conventions described in <a href="http://dx.doi.org/10.1016/j.matchar.2016.04.008">http://dx.doi.org/10.1016/j.matchar.2016.04.008</a>). Data has been captured with a 0.15 um step size.</p> <p>This data was collected within the Harvey Flower EM Suite within the Department of Materials, Imperial College London. The equipment was funded under the Shell-Imperial Advanced Interfaces in Materials Science University Technology Center.</p> <p>Please contact Dr Ben Britton if you have any queries or require further information (b.britton@imperial.ac.uk).</p>

EBSD data was collected on an Oxford Instruments Symmetry detector; data collection and processing was performed using the AZtec software. </p>
HRDIC and EBSD data for the study of early stage plasticity of a Ni-base superalloy
<p>We used High-Resolution Digital Image Correlation (HRDIC) to study the strain localisation and slip activity of a Ni-base superalloy sample, which was subjected to an in-situ tensile test inside a scanning electron microscope (SEM). </p> <p>Displacement data for HRDIC were calculated using two methods: the integrated method, which correlates with the initial reference frame, and the differential method, which correlates with the previous step. Both datasets are available and saved in separate folders in the .zip file named 'HRDIC and EBSD data'.</p> <p>EBSD data for the region of interest (ROI) can be found in the same .zip file along with a Jupyter Notebook to read and visualise to both datasets. </p>

Hawaii peridotite xenoliths EBSD data
<p>Crystal-preferred orientations (CPO) map data for spinel-peridotite xenoliths of 48 spinel-peridotites from four localities in three Hawaiian islands: Salt Lake (SAL) and Pali (PAL) in Oahu, Grove Farm (GF) in Kauai, and Pu'uwai (PU) in Nihau. CPO of olivine, pyroxenes, garnet, and spinel were measured at the SEM-EBSD facility at Geosciences Montpellier by indexing of electron back-scattered diffraction (EBSD) patterns produced by interaction of an incident electron beam with a carefully polished thin section tilted at 70° to the electron beam. Measurements were performed in a JEOL JSM 5600 scanning electron microscope using an acceleration voltage of 17 kV and a working distance of 23 mm. Maps covering almost entirely each thin section were obtained using steps between 15 and 35 μm, depending on grain size. Indexing rates ranged between 80 and 90%. Lower indexation rates (70-80%) were obtained for a few peridotites (GF1B2F, GF4), which show some alteration along grain boundaries due to reaction with the host basalt. Orthopyroxene and clinopyroxene were seldom misindexed for one another. Inaccurate mineral determination and misindexing due to olivine pseudo-symmetry were corrected by careful post-acquisition data treatment controlled by comparing EBSD maps and optical microscopy observations.</p> <p> </p>
