Advances in Scattered Electron Intensity Distribution Imaging for Microstructural Visualization and Correlations with EBSD Measurements
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 ...
متن کاملElectron 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...
متن کاملElectron Capture Detector with Non-Radioactive Electron Source
Gas chromatographs equipped with electron capture detectors (ECD) are widely used for the analysis of electron affine substances. Achieving limits of detection in the low pptv-range, electron capture detectors are the most sensitive detectors available for such compounds. Based on their operating principle, they require free electrons at atmospheric pressure, which are usually generated by usin...
متن کاملPhotoacoustic section imaging with an integrating cylindrical detector
A piezoelectric detector with a cylindrical shape is investigated for photoacoustic section imaging. Images are acquired by rotating a sample in front of the cylindrical detector. With its length exceeding the size of the imaging object, it works as an integrating sensor and therefore allows reconstructing section images with the inverse Radon transform. Prior to the reconstruction the Abel tra...
متن کاملSimulation of a Neutron Detector for Real Time Imaging Applications
Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
