AM Bench (https://www.nist.gov/ambench) is an additive manufacturing benchmarking effort led by the US National Institute of Standards and Technology (NIST). The goal of this effort is to provide the additive manufacturing (AM) modeling community with high fidelity experimental results to aid in development, calibration, and validation of AM models. This talk will provide an overview of all mechanical measurement datasets from AM Bench 2022. All measurements were performed on Inconel 625 fabricated on a commercial laser powder bed fusion (PBF-L) machine. Some of these measurements were performed on the exact specimens characterized in AM Bench 2018, and other measurements used new specimens built on the same machine. There were three mechanical measurements with associated challenges: (1) Subcontinuum Mesoscale Tensile Test [CHAL-AMB2022-04-MeTT], (2) Macroscale Tensile Tests at Different Orientations [CHAL-AMB2022-04-MaTO], and (3) Macroscale Compression at Different Temperatures and Orientations [CHAL-AMB2022-04-MaCTO]. There were two additional mechanical measurements that did not have associated challenges but are publicly available for the modeling community to use: (4) Macroscale Tensile Tests at Different Strain Rates and (5) Macroscale Compression Tests with In-Situ Diffraction at Different Temperatures and Strain Rates.
