Typically, 20 Electron Back-Scatter Diffraction (EBSD), which is sometimes also referred to as Backscatter Kikuchi Diffraction (BKD) is a typcially SEM-based backscatter or transmission electron diffraction technique for retrieving crystallographic orientation and phase information from crystalline materials.

Ebsd

The EBSD system has the added capability of collecting diffraction patterns from samples that are only a few nanometers thick, and are therefore transparent to electrons. This method, known as Transmission Kikuchi Diffraction (TKD), differs from traditional EBSD not only in the requirement that the sample be very thin, but also has an increased special resolution approaching that of a TEM. Since its development in the early 1990s, automated electron backscatter diffraction (EBSD) has become the primary tool to determine the crystal orientation of crystalline materials across a wide variety of material classes (Adams et al., Reference Adams, Wright and Kunze 1993). 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.

The fundamentals of the EBSD technique have been given in a review[24]. Kikuchi patterns can be obtained automatically and the corresponding orientations of the grains and their boundaries can be detected by using orientation imaging mi-croscopy (OIM) software. The angle resolution ob- For EBSD analysis, sample preparation is crucial due to the possibility of escaping of the diffracted electrons from within just a few tens of nanometers of the sample surface. Nevertheless, it is possible to achieve specimen preparation requirements by adhering to some simple recipes.

ebsd Electron Back-scatter Diffraction-EBSD While chemical analysis to determine the gross composition of a sample is often very useful in materials science and related application, it is common that variations in the microstructure of materials can have as much or more of an impact on properties of interest than the chemistry of the bulk sample.

The EBSD image (i.e., the Kikuchi pattern) is made up by a discrete array [x, y] of gray-tone image points (so-called pixels). So we consider a discrete Radon transform whereby the integrals are replaced by sums, and the Radon domain consists of an array of discrete cells on a Cartesian grid (ρ, φ).
