EBSD – Electron Backscattered Diffraction ! Nooshin Mortazavi! Acknowledgement: Dr. Patrick Camus Why we need Electron Backscatterd Diffraction (EBSD)? Because materials properties are “anisotropic”. We all know that the strength of wood varies with the direction of the grain. But the properties of a single crystal also vary with orientation.

EBSD Analysis is a great complement to the excellent capabilities of our X-ray diffraction (XRD) services. While our XRD tools and staff can provide unparalleled information on phase ID, nanocrystalline grain size, thin film thickness and textures; the new capabilities available by EBSD will provide spatial information and help to visualize the

Electron Backscatter Diffraction (EBSD) is a powerful technique capable of characterizing extremely fine grained microstructures in a Scanning Electron Microscope (SEM). Electron Backscatter Patterns (EBSPs) are generated near the sample surface, typically from a depth in the range 10 – 50nm. In order to achieve effective analysis it is imperative to combine high beam current with small

EBSD, Electron Backscatter Diffraction Analysis, is used to perform quantitative microstructural analysis in the Scanning Electron Microscope (SEM), on a millimetre to a nanometre scale.

This could only be accomplished by minimizing pattern indexing calculation time. Electron backscattered diffraction (EBSD) is performed with the scanning electron microscope (SEM) to provide a wide range of analytical data ranging from crystallographic orientation studies, to phase identification to grain size measurements. The specimen’s plane of polish is oriented at a steep angle, about 72°, to horizontal. EBSD provides orientation, misorientation and boundary measurements from a small area (>1 μm) in a crystal and automated EBSD analysis is applied to an increasingly large number of rock-forming minerals.
