  • Structural phase transformations under shock loading are of considerable interest for understanding the response of solids under nonhydrostatic stresses and at high strain-rates. Examining shock-induced transformations from continuum level measurements is fundamentally constrained by the inability to directly identify microscopic processes, and also by the limited number properties that can be directly measured. The latter limitation can be reduced by measuring both shear and compression waves using Lagrangian gauges in combined, compression and shear loading. The shear wave serves as an important, real-time probe of the shocked state and unloading response. Using results from a recent study of CaCO[sub 3],more » the unique information obtained from the shear wave speed and the detailed structure of the shear wave are shown to be useful for distinguishing the effects of phase transformations from yielding, as well as in characterizing the high-pressure phases and the yielding process under shock loading.

  • Various mixtures of metal oxides of compositions which when furnace reacted will yield known high temperature superconductor oxides have been subjected to a range of shock loading conditions to determine parameters leading to their shock-induced chemical synthesis. Recovered samples show x-ray diffraction lines consistent with the formation of the K/sub 2/NiF/sub 4/ structure type crystallographic phase for La/sub 1.85/Sr/sub 0.15/CuO/sub 4/. Studies on the YBaCu system yielded diffraction lines consistent with those for a small amount of YBa/sub 2/Cu/sub 3/O/sub 7/. 3 refs., 3 figs., 1 tab.
