The Grain Boundary Data Archive

The purpose of this site is to archive Grain Boundary Character Distribution and Energy Data, including available raw and processed data, and the programs used for analysis. For more background information, read about the GBDA.


The Materials Science & Engineering Department of Carnegie Mellon University will host a workshop on 3D Microstructures Aug. 19-21, 2019. For details, see:

Workshop on Methods for Three-Dimensional Microstructure Studies


For the 3D data sets, I recommend using Dream.3D (here) for the analysis.

Krzysztof Glowinski's Grain Boundary Toolbox (GBToolbox) is also recommended for analyzing grain boundary symmetry and character and for calculating and plotting quantities from 3D data. MAC, Linux, Windows.

Krzysztof Glowinski's Mathematica scripts for plotting grain boundary distributions. Scripts.

A catalog of the FORTRAN programs used for 2D and 3D computations can be found here.
