Raw and Processed Data to Generate Three-Dimensional Grain Map of Open-Cell Aluminum Foam

Abstract

A three-dimensional grain map of an investment-cast, open-cell, aluminum foam is generated using a combination of experimentally derived and synthetically derived data. Specifically, the experimental data are derived from lab-source and synchrotron-source X-ray computed tomography (CT) and far-field high-energy X-ray diffraction microscopy (ff-HEDM). The grains detected from the experimental measurements are augmented with synthetically generated grains to fully populate a bulk sample of the foam. The raw or partially processed data include an image stack from lab-source X-ray CT measurements of a bulk, in-tact sample of foam; multiple image stacks from synchrotron-source X-ray CT measurements of individual ligaments that were extracted from the bulk sample of foam; and grain output files generated by HEXRD for each measured foam ligament. The processed data include a DREAM.3D pipeline file, supporting data files, and instructions for executing the pipeline to generate the three-dimensional grain-mapped foam reported in the manuscript associated with these data. README.txt files are provided in the data folders, which explain the contents of each folder. The reader is referred to the manuscript associated with this data set for further details regarding the generation of the data.
