Developments in AZtec: New Solutions for EBSD
نویسندگان
چکیده
Electron backscatter diffraction EBSD is a powerful technique applicable to a range of microstructural analyses, including texture, grain size, boundary characterization, phase distribution and inter-phase orientation relationships. The technique is suited to solving an increasing range of analytical problems on the um to mm scale. However, best results are only obtained with a good understanding of how to optimise each element in a complicated analysis chain: from pattern acquisition and processing through to the final interpretation of the output data.

Integrating EBSD and magnetic susceptibility data to decipher intensity of SPO and strain in deformed quartzite
Measurement of intensity of shape preferred orientation (SPO) is an important objective of many structural geological investigations. This not only helps in fabric quantification, but also enables in better correlation of the rock fabric with strain and strain-intensity variations that may have implications in regional tectonics. There are several methods available to quantify SPO – e.g. Launea...
متن کاملA Gessel-Viennot-Type Method for Cycle Systems in a Directed Graph
We introduce a new determinantal method to count cycle systems in a directed graph that generalizes Gessel and Viennot’s determinantal method on path systems. The method gives new insight into the enumeration of domino tilings of Aztec diamonds, Aztec pillows, and related regions.
متن کاملMeasurement of the five-parameter grain boundary distribution from planar sections
Although EBSD is essentially a surface measurement technique, strategies have been developed to extend its capabilities to the char-acterisation of microstructure in three dimensions. These developments have been able to be realised because of advances in both EBSD technology and computing power have rendered the collection of large data sets a routine matter. There are several scientific motiv...
متن کاملElectron 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 ...
متن کاملAn Alternative Technique for Proving the Aztec Diamond Theorem and Other Applications
A new technique, called the superimposition technique, is used to prove various combinatorial identities, including the Aztec Diamond Theorem. The technique involves superimposing matchings of a graph and a smaller subgraph, and then partitioning the united graph again into matchings of two subgraphs. Applications of the technique include weighted Aztec diamonds, holey Aztec rectangles, and pla...
