    • AM Bench 2022 Residual Elastic Strain, Residual Stress, and Part Deflection Measurements for IN718 3D Builds

    Metadata Updated: June 7, 2023

    The following data files include residual elastic strain, residual stress, and part deflection results associated with the 2022 Additive Manufacturing Benchmark test series (AM Bench 2022) AMB2022-01 benchmark on laser powder bed fusion (LPBF) 3D builds of nickel-based superalloy IN718 test objects. The AM builds were performed on the NIST Additive Manufacturing Metrology Testbed (AMMT). The residual elastic strains were measured using synchrotron X-ray diffraction at the Cornell High Energy Synchrotron Source (CHESS) and neutron diffraction at the Oak Ridge National Laboratory (ORNL) High Flux Isotope Reactor (HFIR). Residual stresses were characterized using the contour method by UC Davis and Hill Engineering. Part deflection after partial cutting of the build part off the build plate was measured at NIST. Detailed descriptions of the build process parameters, scan pattern, heat treatment, and descriptions of all of the AMB2022-01 measurements are provided on the AMB2022-01 challenge description webpage (https://www.nist.gov/ambench/amb2022-01-benchmark-measurements-and-challenge-problems). Due to the time-sensitive nature of the AM Bench challenge problems, those measurements and analyses were prioritized. The challenges that this data publication address are:Residual elastic strain (CHAL-AMB2022-01-RS): Residual elastic strain components at select locations internal to the bridge structure, corresponding to synchrotron X-ray diffraction measurements. Part deflection (CHAL-AMB2022-01-PD): Deflection of the as-built (no heat treatment) bridge structure after it is partially separated from the build plate.Additional datasets that are not required for the challenges will be added soon.
