TEXTURE ANALYSIS WITH MTEX

摘要

This year's MTEX short course - again sponsored by DMG - focused on EBSD data analysis. Due to the sudden illness of Helmut Schaeben, the teaching arrangements had to be changed at the last minute. Fortunately, the initiator of MTEX (an open source MATLAB toolbox for quantitative texture analysis), Ralf Hielscher (Technische Universitat Chemnitz), and a major contributor to MTEX, Florian Bachmann (TU Bergakademie Freiberg), were available to assist David Mainprice (Montpellier) in teaching this course. As usual, the course was divided into lectures on the theory and programming details behind MTEX and extensive practical sessions under the guidance of the lecturers. Some practical sessions were concerned with interactive problem solving and the development of scripts based on user-proposed problems, such as removing and merging grains. Lectures covered the EBSD technique, crystallography and crystal geometry, orientation and misorientation distribution functions, microstructure and grain analysis, Schmid factor analysis, and anisotropic physical properties of single crystals and polycrystalline aggregates. Fourteen students attended the course - they came from a wide range of European countries: Austria, Belgium, France, Germany, Norway, UK, and Switzerland, and about 1/3 were women. Students, mostly PhD students, were mainly from the geosciences, with some from materials sciences, and a few participants were based in industry or university electron microscopy facilities.
