| Abstract Scope |
Mechanisms of void formation during extreme loading conditions in polycrystalline materials are investigated using non-destructive 3D microstructure characterization to correlate damage, microstructural features, and local strain states. Pure alpha titanium is machined into 3 mm tall cones with diameter from 0.68 mm to 1.2 mm that are characterized with High Energy Diffraction Microscopy (HEDM) in pre and post shock loaded states. Shock experiments are performed under titanium’s alpha to omega transition, but above the threshold for damage initiation. Python-based software HEXOMAP is used to reconstruct orientations and strains from HEDM data, so that microstructural and strain data can be correlated with damage. Recent advances in measurement technology at the Advanced Photon Source make resolving twins and strain states possible. |
