| Abstract Scope |
Commercially pure alpha-Ti was shocked loaded at 296 m/s and 340 m/s using a gas-gun flyer plate impact to achieve incipient spallation. The microstructure of these deformed samples is compared to their undeformed state measured ex-situ via near-field High-Energy Diffraction Microscopy. From the voxelized microstructure reconstruction, the five-dimensional grain boundary characterization is computed and compared across deformed and undeformed states. The evolution of the grain boundary character distribution is tracked at selected slices along the loading axis for the 340 m/s shock case while a volume measurement is done for the 296 m/s shock case. Computed distributions are compared to a volume measurement of an undeformed alpha-Ti as a representative initial state. |
