MTEX is a free Matlab toolbox for analyzing and modeling crystallographic textures by means of EBSD or pole figure data. It is developed on a free and opensource basis by an interdisciplinary
team
of material scientists, geologists and mathematicians.

Denoising Orientation Maps
In this section we demonstrate how random errors can be significantly reduced using denoising techniques.

Martensite Parent Grain Reconstruction
Here we demonstrate the tools MTEX offers to reconstruct a parent austenite phase from a measured martensite phase.

MTEX GUI
... is a graphical user interface to MTEX that allows to perform many analysis step in a non programming way.
MTEX2Gmsh
... allows to generate meshes from EBSD data. It is intended to perform Finite Element Analysis (FEA) at grain scale on polycrystal imaged by EBSD.
phaseSegmenter
... enables the discrimination and segmentation of crystallographically identical/similar phases with grains of distinct orientation and slight compositional differences. The program uses reindexed EBSD datasets and EDS elemental data to compute grain-median compositional differences between grains of the phases in question and segments these by determination of an optimal threshold value.
ORTools
... is a function library for orientation relationship (OR) discovery, advanced OR analysis and the plotting of visually stunning and informative publication-ready figures particular to microstructures undergone partial or full orientation-related phase transformation. ORTools serves as an add-on to the phase transition functionalities in MTEX.
crystalAligner
... is an experimental tool that allows to determine the alignment of one or two crystal directions or plane normals of arbitrary crystal orientation and structure with the coordinate system of a scanning electron microscope. The program outputs instructions for stage tilt and rotation for crystal alignment.
