Statistics of deformation twinning in Cu/Nb nanolamellar composites measured using electron backscatter diffraction (EBSD)

Electron Backscatter Diffraction (EBSD) Technique and Materials Characterization Examples

The term “electron backscatter diffraction” (EBSD) is now synonymous with both the scanning electron microscope (SEM) technique and the accessory system that can be attached to an SEM. EBSD provides quantitative microstructural information about the crystallographic nature of metals, minerals, semiconductors, and ceramics—in fact most inorganic crystalline materials. It reveals grain size, grai...

Distinguishing Biologically Controlled Calcareous Biomineralization in Fossil Organisms Using Electron Backscatter Diffraction (EBSD)

Although carbonate-precipitating cyanobacteria are ubiquitous in aquatic ecosystems today, the criteria used to identify them in the geological record are subjective and rarely testable. Differences in the mode of biomineralization between cyanobacteria and eukaryotes, i.e., biologically induced calcification (BIM) vs. biologically controlled calcification (BCM), result in different crystallogr...

Crystallographic preferred orientations analysis of quartz crystals in Psammite using electron backscatter diffraction,western Ireland

The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) nearLetterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

Textural analysis of a microcrystalline quartz using X-Ray and Electron Backscatter Diffraction (EBSD) techniques

An unusual microcrystalline quartz texture has been recognized in the investigation of pervasively silicified ore-bearing horizons occurring in the uppermost part of carbonate platform sequences of different ages (from Precambrian to Mesozoic) and of different geotectonic settings. This peculiar texture has been labeled “grid-work texture”, and derives only by a rather fast and preferred crysta...
