The profiles of shock waves in titanium have been measured at pressure amplitudes ranging from 58 to 249 kbar. At 140 kbar, a splitting of the shock wave is observed. This splitting is a consequence of a first-order phase transition. The pressure of the phase transition, which is equal to the amplitude of the first shock wave, is 119 kbar. The velocity of the first shock wave is 5.4 km/s, and the duration of the phase transition is ~0.25 μ$.
