For this dataset, 607 unique kovar samples were manufactured using Laser Powder Bed Fusion (LPBF) over 304 unique sets of LPBF process parameters. Electron Backscatter Diffraction (EBSD) data was collected for each sample using one of two methods, called here "Version 1" and "Version 2." For version 1 samples, two kovar specimens were created for each set of LPBF process parameters--one ground and one unground prior to EBSD collection. For version 2 samples, two kovar specimens were created for each set of LPBF process parameters--one horizontally oriented and one vertically oriented. Other methodological distinctions between version 1 and version 2 samples are highlighted in the methods section of our Readme. The dataset consists of raw channel text files (ctf), usable header information and EBSD data points extracted from each ctf, and LPBF build process parameters for each additively manufactured sample. The high throughput EBSD innovations used to generate this data are thoroughly described in our corresponding paper, "High Throughput Microstructural Characterization using Automated Electron Backscatter Diffraction."
