Abstract: The structure of bismuth samples after shock-wave loading at pressures of 0.7–2.4 and 22–32 GPa was studied. Before loading, samples were at room temperature or heated to 230–240$^\circ$C. Loading by a pressure of 1.5–2 GPa at an initial temperature of 233–240$^\circ$C led to a structural change in bismuth, indicating melting of the sample in a shock wave. The time of shock-wave action was $\approx$ 0.7 $\mu$s.

Keywords: bismuth, shock wave, melting.
