Abstract Scope This challenge is a follow-on from AMB2022-01 laser powder bed fusion (PBF-LB) alloy Inconel 718 in the as-built condition (no heat treatment). Eight continuum-but-miniature tensile specimens were quasi-static uniaxially tensile tested according to ASTM E8. Calibration data given includes all processing and microstructure data from AMB2022-01. 3D serial sectioning electron backscatter diffraction (EBSD) data was collected for the present challenge, which consisted of a request for mechanical properties predictions of all eight specimens. Detailed descriptions of the trends in analysis and comparisons between the round-robin submission methodologies will be briefly discussed. The measured mechanical property data will be disseminated consistent with data reduction techniques outlined in the ASTM Designation E3076-18. Along with this, alternative approaches for data reduction outside of this standard will be discussed.
