Observation of a two-wave shock configuration in zirconium

The profiles of shock waves with pressure amplitudes from 40 to 280 kbar in zirconium have been measured. Between 93 and 138 kbar, a splitting of the shock wave is observed. This splitting is associated with a first-order phase transition. The phase-transition pressure, equal to the amplitude of the first shock wave, is 62-67 kbar. The transition takes ~0.25 μβ.
