EBSD Polygonizer: Facilitating Realistic Microstructural Modelling

EBSDPolygonizer is a MATLAB-based app designed to transform EBSD grain data into polygonal representations. In this conversion, each grain is represented by a distinct polygon. This transformation allows for the direct utilization of real microstructures as geometries in finite element (FE) models and automated assignment of material parameters and boundary conditions to individual grains.

Features

• Data Import and Export: Support text files exported from AztecCrystal, HKL Channel 5 or user-written text file.
• Polygonization: Transform raster EBSD data into meaningful polygonized data structures.
• Plotting: Plotting capabilities to visualize EBSD maps, neighboring grains, grain boundaries, and vertices.

Installation

• Download and run the MATLAB installer file EBSD Polygonizer.mlappinstall. Alternatively, click on the Install App icon in the toolbar under the APPS ribbon in MATLAB, navigate to the installation file and install.
