Features

• Crystallographic geometry: all kind of symmetries, different Euler angle conventions, import from crystallographic information files (CIF)
• ODF modelling: any composition of uniform, unimodal, fibre and Bingham ODFs, pole figure simulation, EBSD simulation
• ODF analysis: modal orientations, difference ODFs, volume portions, entropy, texture index, Fourier coefficients
• Pole figure analysis: 28 data formats, data correction
• Pole figure to ODF inversion: works for all symmetries, all measurement grids, incomplete and not normalized pole figures, automatic ghost correction, zero range method
• EBSD data analysis: 8 data formats, data correction
• Grain detection: grain boundary analysis, missorientation analysis
• ODF estimation from EBSD data: automatic kernel width selection, arbitrarily many individual orientations
• 3D EBSD Data Analysis: volume visualization, 3d grain reconstruction, topology of 3d grains, i.e. boundaries, neighboring grains, etc.
• Material tensors: average tensors from EBSD data and ODFs
• Elasticity tensors: elastic stiffness tensor, elastic compliance tensor, Young's modulus, shear modulus, Poisson's ratio, linear compressibility, compressional and shear elastic wave velocities, wavefront velocities
• High quality plots: pole figures, inverse pole figures, ODF sections, orientation maps
• Batch processing of many data sets: allows scripting to handle multiple data sets automatically
• Extensive doumentation: 800 pages inline documentation, examples, tutorials, created with dochelp

New Contributers Welcome

Do you think about a new feature in MTEX. Please let us know, but don't hesitate to have a quick look into the internals of MTEX. Maybe your idea is more easily implemented than you might have dreamed of. When developing MTEX we try to keep it as flexible and extensible as possible. So give your ideas a try and become a contributor of MTEX.

Reference Paper

In case you use MTEX in your research, we would greatly appreciate if you added the corresponding reference from the list of reference papers to your publications.
