Abstract:
Results of X-ray diffraction studies of shock-compressed single crystals indicate the rotation of crystallites by $\sim 3^\circ$ ahead of the shock-wave front both in the plastic-flow and elastic-compression regions. Two dynamic states of the lattice have been detected. The brightness of reflections evolves with time. The position of the first dynamic reflection coincides with the position of a reflection from the initial structure. The second reflection corresponds to an equilibrium-compressed structure. Possible reasons of the formation of these two states of the lattice have been discussed.
