N2 - Textured, high-purity hafnium has been shock loaded at 5 and 11GPa, below the pressure reported for the αω phase transformation, 23 GPa. The specimens were "soft caught" for post-shock characterization. Substructure of the shocked materials was investigated through transmission electron microscopy and texture evolution due to shock loading was probed with neutron diffraction. The deformation behavior of as-annealed hafnium under quasi-static conditions was compared to its response following shock prestraining. Reload response was correlated to defect generation and storage due to shock loading and compared with observations in other HCP metals such as Ti and Zr.
