An experimental technique has recently been developed to characterize reactive metals, including plutonium (Pu) and cerium, using electron backscatter diffraction (EBSD). Microstructural characterization of Pu and its alloys by EBSD had been previously elusive primarily because of the extreme toxicity and rapid surface oxidation rate associated with Pu metal. The experimental technique, which i...

Microstructure reconstructions resulting from diffraction contrast tomography data of polycrystalline bulk strontium titanate were reinvestigated by means of electron backscatter diffraction (EBSD) characterization. Corresponding two-dimensional grain maps from the two characterization methods were aligned and compared, focusing on the spatial resolution at the internal interfaces. The compared...

the formation of atoll garnet in the ardara aureole, nw ireland, is discussed using the textural, chemical and electron backscatter diffraction (ebsd) data. textural evidence suggests the possibility of incipient of garnet replacement from the core. in addition, the presence of staurolite and andalusite in the core of small atoll garnets as well as the occurrence of sillimanite in the core of l...

By simply crushing mineral grains, suspending the powder in a liquid, and dispersing the suspension on a suitable substrate, it is possible to collect adequate compositional and structural information to identify an unknown phase using a scanning electron microscope (SEM) equipped with an energydispersive X-ray spectrometer (EDS) and an electron backscatter diffraction system (EBSD). This techn...

Electron backscatter diffraction (EBSD) has evolved into a well-established tool for microstructural characterization by providing quantitative information on crystallographic orientation and phase content and distribution. The rapid acceptance of EBSD as an analytical technique has been driven, in part, by the highly informative contrasts used to create different micrographs which effectively ...

The spatial resolution of electron diffraction within the scanning electron microscope (SEM) has progressed from channelling methods capable of measuring crystallographic characteristics from 10 μm regions to electron backscatter diffraction (EBSD) methods capable of measuring 120 nm particles. Here, we report a new form of low-energy transmission Kikuchi diffraction, performed in the SEM. Tran...

Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates. EBSD data are compared for biogenic aragonite and calcite in the common blue mussel, Mytilus edulis, using different types of resin and thickne...

The grain boundaries of three Laves phase-related body-center-cubic (bcc) solid-solution, metal hydride (MH) alloys with different phase abundances were closely examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and more importantly, electron backscatter diffraction (EBSD) techniques. By using EBSD, we were able to identify the alignment of the crystallograp...

The microtexture of differently prepared Ba-hexaferrite samples is investigated by means of electron backscatter diffraction (EBSD). Kikuchi patterns are obtained with a high image quality, enabling a spatial resolution of the EBSD maps of about 20 nm. The spatially highly resolved EBSD mappings provide additional information (individual grain orientation, misorientation angles, grain size dist...

Within the past decade Electron Backscatter Diffraction (EBSD) has experienced wide acceptance in metallurgical and geological labs. It is a Kikuchi diffraction device based on the SEM that enables individual grain orientations, local texture, point-to-point orientation correlations, and phases to be determined routinely at a sub-grain size level on the surfaces of bulk polycrystals while explo...
