  • Powder compacts of magnetite and zirconia have been subjected to controlled, quantitative high pressure shock loading at peak pressures from 5-27 GPa. X-ray diffraction lines are broadened, indicating considerable reduction of the crystallite size and introduction of residual microstrain. At higher pressures, different shock-induced reactions are observed in these two materials. 10 refs., 2 figs., 2 tabs.
  • Experiments utilizing infrared radiometry have yielded measurements of the time resolved temperature of shocked explosive PBX-9404. The results on bare charges indicate the presence of hot spots whose temperature varies strongly with pressure. Interpretation of the results on bare charges is consistent with current theories of heterogeneous initiation. Also, several experiments with transparent, impedance matched overlays were successful in measuring the temperature of the explosive as the pressure at the interface evolved.
  • Ni-based HAYNES[sup (R)] 230[sup TM] ALLOY has been studied to determine the effect of shock loading on the post-shock quasistatic and dynamic mechanical response, and microstructural evolution. The compression properties of this material was studied in both the as-received and shock-loaded conditions at strain rates from 10[sup [minus]3]/s to 3000/s, and 77 and 293K. Damage evolution was documented via TEM, and correlated with the observed mechanical response. Changes in the deformation mechanisms and second phase distributions resulting from the shock pre-straining and subsequent testing are correlated with changes in the strain hardening behavior of the materials. Comparison of these resultsmore » with shock loading results on pure Ni revealed distinct differences in strengthening and defect storage mechanisms.
