Sound velocity in natural shock-compressed uranium in a pressure range of 20–260 GPa

This paper presents the results of sound velocity measurements performed in natural uranium during the high-rate deformation of sound in $\alpha$-and $\gamma$-phase regions, as well as in the melting region at the shock front. The processes are recorded using the manganin sensor method (range 20–110 GPa) and the indicator method (range 70–260 GPa). In the region of the solid uranium phase, changes in Poisson's ratio, Young's modulus, bulk modulus, and shear modulus along the uranium shock adiabat are determined.
