| Abstract: | Recover devices of samples treated under super-pressure loading by quasi-spherical converging shock wave using nitromethane liquid explosive were studied. High-pressure acting on samples were produced by shock wave front converging in metallic ball. Destruction and metallograph of metallic ball after shock treatment were studied. The results show that shock waves front is spherical Symmetry and recovery of samples is reliable. The pressure near the center of metal ball is higher than 207 GPa. The devices can be significantly used in investigating recover samples of materials loaded by ultrahigh pressure shock waves. |
