AM Bench 2022: Cross sectional microstructure of single laser tracks produced using different processing conditions and 2D arrays of laser tracks (pads) on solid plates of nickel alloy 718

The following data files include microstructure measurement results associated with the 2022 Additive Manufacturing Benchmark test series (AM Bench 2022) AMB2022-03 set of benchmarks. These AMB2022-03 benchmarks explore a range of individual and overlapping melt pool behaviors using individual laser tracks and 2D arrays of laser tracks (pads) on solid metal IN718 plates. For the individual laser tracks, a range of laser parameters was used, with variations in laser power, speed, and spot diameter. For the laser pads, the laser scan patterns and most of the laser parameters match those used for the 2.5 mm legs from the AMB2022-01 3D builds. The laser tracks and pads were cross sectioned at different locations and examined using scanning electron microscopy (SEM) electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS). Descriptions and measurement data for all of the other AMB2022-03 measurements may be found on the AM Bench website at www.nist.gov/ambench.The AM Bench measurements metadata catalog provides both a web search interface and API access to extensive linked data associated with these measurements (see Data Access link to explore this related resource). The SciServer AM Bench collaborative compute platform provides a mechanism for exploring and analyzing the AM Bench datasets directly on a data server without the need to download large datasets (see Data Access link to explore this related resource).
