EXAFS measurements of vanadium shocked to ~0.4 Mbar yield the compression and temperature in good agreement with hydrodynamic simulations and shock-speed measurements. In laser-shocked titanium at the same pressure, the EXAFS spectrum indicates the ?-Ti to ?-Ti crystal-phase transformation, known to occur below ~0.1 Mbar for slower shock waves.
