    • AM Bench 2022 challenge problem Subcontinuum Mesoscale Tensile Test (CHAL-AMB2022-04-MeTT)

    Metadata Updated: September 30, 2023

    One additively manufactured (AM) laser powder bed fusion (PBF-L) Inconel 625 mesoscale tensile specimen (gauge dimensions approximately 0.2mm x 0.2 mm x 1mm) was extracted from build AMB2022-CBM-B1 specimen TH1 and tested at room temperature using a quasistatic strain rate of 0.001/s to failure.  Microstructure was measured using x-ray computed tomography (XRCT) and scanning electron microscopy (SEM) techniques on the specimen gauge section or adjacent material.  Large-area electron backscatter diffraction was used to measure crystallographic texture and grain size/morphology of the entire gauge section and two orthogonal planes.  Backscatter electron imaging was used to characterize the subgrain structure and assess recast layer thickness from electric discharge machining.  Electron channeling contrast imaging was used to estimate dislocation density.  XRCT was used to analyze the pore population as well as uncertainty in cross-sectional area for stress calculations.  Literature sources were used to estimate phase fraction, residual stress, and the single crystal C-tensor.  All processing details, specimen preparation details, tensile test method details, and microstructure measurements are provided. Predictions are requested for the subcontinuum stress strain behavior and fracture pathway of one as-built IN625 meso-scale specimen.
