AMB2025-02 Macroscale Quasi-Static Tensile Tests of PBF-L IN718

Description

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 excised from the same size legs (2.5 mm width) of one original AMB2022-01 specimen (AMB2022-718-AMMT-B7-P4). Excised tensile specimens were quasi-static uniaxially tensile tested according to ASTM E8 (strain rate 1*10-3 sec-1, 3 mm gauge length custom contact extensometer). Calibration data given includes all processing and microstructure data from AMB2022-01 (https://www.nist.gov/ambench/am-bench-2022-challenge-problems-and-measurement-results), including 3D serial sectioning electron backscatter diffraction (EBSD) data (https://doi.org/10.18434/mds2-2767). Material property data such as elastic mechanical properties are not provided.

0 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). As seen in Figure 1, eight continuum-but-miniature tensile specimens were excised from the same size legs (2.5 mm width) of one original AMB2022-01 specimen (AMB2022-718-AMMT-B7-P4). Excised tensile specimens were quasi-static uniaxially tensile tested according to ASTM E8 (strain rate 1*10-3 sec-1, 3 mm gauge length custom contact extensometer).
