X-Ray diffraction measurements of plasticity in shock-compressed vanadium in the region of 10-70 GPa

Abstract:

We report experiments in which powder-diffraction data were recorded from polycrystalline vanadium foils, shock-compressed to pressures in the range 10 – 70 GPa. Anisotropic strain in the compressed material is inferred from the asymmetry of Debye-Scherrer diffraction images, and used to infer residual strain and yield strength (residual von Mises stress) of the vanadium sample material. We find residual anisotropic strain corresponding to yield strength in the range 1.2 GPa – 1.8 GPa for sho...
