Electron back scattered diffraction

Presently, methods are being developed that focus on the use of superresolution confocal Raman microscopy (CRM), electron back-scattered diffraction (EBSD), and, in combination with high-resolution XRD, to identify and measure the stress distributions of structures and defects that control... 

Spectroscopic measurements (intensity, phase of incident, and emitted photons), which yield chemical, electronic, structural, and thickness information, for example, by pho-ton/photon effects (e.g. ellipsometry) or photon absorption (e.g. reflectome-try) or structural information (e.g. from Extended X-ray absorption fine structure (EXAFS) or Electron Back Scatter Diffraction EBSD).

Compared to the reference alloy, the Zr-containing material revealed up to breakaway no broccoli effect and only minor macroscopically visible spallation at the specimen corners and edges (Fig. 7.3), in agreement with the mass change data in Fig. 7.1. The suppression of the broccoli effect by Zr has previously been related to tying up the carbon impurity into more stable carbide [12]. It should be noted that no Cr carbide formation was detected in the alloy -l-Zr . The microstructures of the scales after 1000 h oxidation are shown in Fig. 7.8. Compared to alloy MRef the alumina scale on alloy -FZr is thicker and contains zirconia inclusions and porosity in the outer part. Studies of the scale grain structure were performed using electron back-scattered diffraction (EBSD). The studies revealed (Fig. 7.9) that the alumina...

Micrographs obtained by EPMA are shown in Figure 4. The sample in this case was VPO with 10% amorphous silica as the hard phase. This composition was prepared by spray drying an aqueous slurry with about 40% solids made of l-2 im particles of the VPO catalyst precursor and polysilicic acid. The back-scattered image shows all elements present in the porous microsphere. The X-ray image of silicon clearly shows this element concentrated exclusively on the periphery of the microsphere. Independent X-ray diffraction and electron diffraction analysis of the peripheral layer of the microspheres showed that the silicon is present as amorphous silica.
