Crystal orientation and detector distance effects on resolving pseudosymmetry by electron backscatter diffraction

نویسندگان

چکیده

Accurately indexing pseudosymmetric materials has long proven challenging for electron backscatter diffraction. The recent emergence of intensity-based approaches promises an enhanced ability to resolve pseudosymmetry compared with traditional Hough-based approaches. However, little work been done understand the effects sample position and orientation on pseudosymmetry, especially Thus, in this crystal detector distance a model tetragonal ZrO 2 ( c / = 1.0185) material are quantitatively investigated. orientations that easiest most difficult correctly index identified, effect confidence is characterized, these trends analyzed basis appearance specific zone axes diffraction patterns. findings also point clear benefit shorter distances resolving using

Magnetic Domain Structure and Crystal Orientation Revealed by a Forescatter Detector and Electron Backscatter Diffraction

Imaging magnetic domains for soft magnetic materials using scanning electron microscopy (SEM) typically requires a specially modified setup. These modifications can include higher beam acceleration voltages, modifications of the sample and detector geometry, and/or specialized detectors to detect the spin polarization of secondary electrons [1,2]. In this research, a method is presented for ima...

Dynamical effects of anisotropic inelastic scattering in electron backscatter diffraction.

We present a model which describes the appearance of excess and deficiency features in electron backscatter diffraction (EBSD) patterns and we show how to include this effect in many-beam dynamical simulations of EBSD. The excess and deficiency features appear naturally if we take into account the anisotropy of the internal source of inelastically scattered electrons which are subsequently scat...

Electron backscatter diffraction in materials characterization

Electron Back-Scatter Diffraction (EBSD) is a powerful technique that captures electron diffraction patterns from crystals, constituents of material. Captured patterns can then be used to determine grain morphology, crystallographic orientation and chemistry of present phases, which provide complete characterization of microstructure and strong correlation to both properties and performance of ...

Biomineral electron backscatter diffraction for palaeontology

Electron backscatter diffraction (EBSD) originated in materials science and has transferred to biomineral research providing insight into fossil and modern biominerals. An electron microscopy technique, EBSD requires a fine polished sample surface where the electron beam diffracts in the first few lattice layers, identifying mineral, polymorph and crystallographic orientation. The technique is ...

Microstructure of Flash Processed Steel Characterized by Electron Backscatter Diffraction

Flash processing is a new heat treatment process being developed to produce steel with relatively high strength and ductility. It involves rapidly heating steel sheet or strip to a temperature in the austenite range and quenching; the entire thermal cycle takes place within 15 seconds. The resulting microstructure is fine and difficult to resolve using standard metallographic techniques. In thi...
