Features of solid-phase transformations induced by shock compression

The results of physicochemical studies of solid-phase transformations under shock compression are analysed. The characteristic time of phase transitions and chemical reactions in shock-compressed solids found experimentally does not exceed one microsecond. Possible reasons for ultrafast atom diffusion are discussed. Hydrodynamic mixing of reactants is believed to be the most feasible mechanism. Prospects for basic and applied research in the field are outlined.
