  Electron backscatter diffraction - Wikipedia, the free encyclopedia
EBSD can be used to index and identify the seven crystal systems, and as such it is applied to crystal orientation mapping, defect studies, phase identification, grain boundary and morphology studies, regional heterogeneity investigations, material discrimination, and using complimentary techniques, physico-chemical identification.
Experimentally EBSD is conducted using a scanning electron microscope (SEM) equipped with a backscatter diffraction camera.
The diffraction camera is essentially a focal plane CCD coupled with a phosphor screen, which is inserted into the specimen chamber of the SEM at an angle greater than or equal to 90° to the pole piece.

We show that the EBSD technique may be used to reveal the relative orientation of an epilayer with respect to its substrate (a 90 degree rotation between the GaN epilayer and sapphire substrate is observed) and to determine its tilt (the GaN epilayer was found to be tilted by 12+-3 degrees towards [10-10]GaN).
EBSD is presently used predominantly in metallurgy [1], being applied to the measurement of texture, i.e., the mapping of the orientation of individual grains in polycrystalline material [1-2], and for the identification of the phase of crystallites whose composition have been identified previously by x-ray spectrometry [3].
We have illustrated that the EBSD technique may be used to reveal the relative orientation of a GaN epilayer with respect to its substrate and to determine its tilt.

 Electron Backscatter Diffraction - Event booking information - Royal Microscopical Society (RMS)
EBSD is a powerful scanning electron microscope based diffraction technique that provides quantitative crystallographic analysis from regions as small as a few tens of nanometers at the surface of bulk samples.
EBSD is firmly established as an indispensable tool for the quantitative characterisation of crystalline samples and is used extensively in many materials research institutions.
EBSD is being brought to bear on an ever expanding range of applications in metals, ceramics and semiconductors, including both man-made and natural materials.

 Creait Network | Electron backscattered electron diffraction (EBSD)
EBSD is a method for determining the crystallographic orientation of mineral or metal grains relative to one another in a polished thin section.
The EBSD technique is a very powerful researchers’ tool, especially when the spatial resolution of the SEM is taken into account.  When identity of a mineral is known, the pole geometry can determine the orientation of the lattice to within a single degree.
For example, it would be an easy task for EBSD to identify lattice twin planes (not otherwise visible), as well as subtle alignments due to strain or magmatic flow.

 EBSD on ultrafine grained steel
The basic result of this study is that the grain size characterization of polycrystalline microstructures with ultrafine grains requires the use of the high resolution EBSD method in conjunction with a careful analysis of the grain boundary character.
They found that the spacing between large angle grain boundaries as observed in the EBSD maps perpendicular to the rolling direction was similar to the subgrain size after a true strain of about 2.
By using a novel combination of EBSD map analysis and the mean linear intercept method the sizes of grains and subgrains were separately obtained.

 Advanced Chemical and Materials Analysis - Index
The EBSD technique (also known as Backscattered Kikuchi Diffraction, BKD) was first developed by Alam and co-workers in 1954, who described some diffraction patterns and called them “wide-angle back-scatter Kikuchi patterns”, in recognition of related diffraction phenomena reported by Kikuchi in the 1920’s.
However, it was not until the 1970’s that Venables and co-workers applied EBSD to metallurgical microcrystallography, paving the way for a more widespread application of EBSD to the materials sciences in the ensuing 20 years.
EBSD software automatically locates the positions of individual Kikuchi bands, compares these to theoretical data about the relevant phase and rapidly calculates the 3-D crystallographic orientation.

 EBSD explained   (Site not responding. Last check: 2007-11-01)
Electron Backscatter Diffraction (EBSD) is a technique which allows crystallographic information to be obtained from samples in the scanning electron microscope (SEM).
In EBSD a stationary electron beam strikes a tilted crystalline sample and the diffracted electrons form a pattern on a fluorescent screen.
In the last ten years EBSD has become a well established technique for the SEM, and obtaining crystallographic information from samples is now both routine and easy.

 Events Details - Electron Backscatter Diffraction Meeting
EBSD is a scanning electron microscope based technique that allows automatic evaluation of orientations of microstructural constituents on the scale of a few tens of nanometres.
The high resolution of EBSD, particularly with modern FEG SEMs, combined with the ability to characterise large areas of solid samples, overcomes some of the limitations of X-ray diffraction and TEM methods, and the development of improved CCD cameras and faster data processing now allows very rapid data acquisition.
EBSD is now regarded as an indispensable tool for the quantitative characterisation of crystalline materials and is installed in the majority of materials research institutions.

 Introduction
The EBSD Network is a users’ group which was set up in October 2000 to bring together those workers from academe, government laboratories and industry with a common interest in exploiting this versatile technique in order to solve materials problems.
The value of EBSD to the science community is that it is used as an increasingly important tool to probe crystallographic and orientation related phenomena on a scale that was hitherto not possible.
A recommended general method for preparing many specimens for EBSD (particularly minerals but not aluminium or magnesium alloys) is final polishing in colloidal silica, since this medium does not introduce the harsh mechanical damage associated with diamond polishing.

 EBSD Identification of Particles
Recently an EBSD Phase ID system has been commercially developed that enables the rapid identification of the crystallographic phase of unknowns in the scanning electron microscope.
In this investigation, we looked at the application of the EBSD Phase ID system to the phase identification of individual micrometer and submicrometer particles rather than the conventional EBSD samples that consist of bulk samples with flat polished surfaces.
Results and future plans: The results from the EBSD analysis of individual particles indicate that the EBSD system was very successful in identifying the phases of individual submicrometer particles with relatively high average Z as shown in Figure 1.

 Nordisk InnovationsCenter - Seminar on EBSD on metals in industrial applications
EBSD (Electron Back Scatter Diffraction) is a very powerful technique for microstructural characterisation and analysis of crystalline materials, up till now mainly used in metallography and geology.
Industry and universities in the rest of the world routinely use EBSD in research and development and although many of the metal producing companies in the Nordic countries have EBSD equipment attached to their scanning electron microscope, the use of EBSD has been limited.
The EBSD suppliers will have their own session in which they can describe their products and future trends for the technique.
