Abstract
Shock-compression experiments were performed on NbH0.75 to 150 GPa and TaH0.50 to 210 GPa using a 25-mm propellant gun and a 20-mm two-stage light-gas gun. Linear relations were found between the shock velocity U-s and the particle velocity u(p): U-s=4.79+1.14u(p) for NbH0.75 and U-s=3.44+1.23u(p) for TaH0.50. Compression curves of interstitial hyd rogen, deduced from the Hugoniots of these hydrides and original metal s, come close to the one calculated for metallic hydrogen. These data provide additional examples of a universal compression behavior of hyd rogen in a metallic environment.
