Resumo

The structure of bismuth samples after shock-wave loading at pressures of 0.7–2.4 and 22–32 GPa was studied. Before loading, the samples were at room temperature or heated to 230–240°C. Loading by a pressure of 1.5–2 GPa at an initial temperature of 233–240°C led to a structural change in bismuth, indicating melting of the sample in the shock wave. The time of shock-wave loading was ≈0.7 μs.
