Macroscopic stress-strain responses can often be captured by a non-unique set of micromechanical material parameters. As a result, confidence in full-field micromechanical results, necessary for predicting properties such as strength, ductility, and fatigue-life, is reduced. One means to address this issue is to use micromechanical experimental data, such as lattice strain data collected from synchrotron X-ray sources. Here we present lattice strain data collected at the Cornell High Energy Synchrotron Source during in situ compression testing of additively manufactured (AM) Inconel 625. This data is used to calibrate ExaConstit, a high-performance crystal plasticity finite element method code developed as part of the DOE ExaAM project for locally accurate property prediction of metal AM components. Micromechanical response of the AM Inconel 625 from both experiment and simulation is discussed.
