Title: Structural Transformation and Melting in Gold Shock Compressed to 355 GPa

Abstract

Gold is believed to retain its ambient crystal structure to very high pressures under static and shock compression, enabling its wide use as a pressure marker. Our in situ x-ray diffraction measurements on shock-compressed gold show that it transforms to the body-centered-cubic (bcc) phase, with an onset pressure between 150-176 GPa. Liquid/bcc coexistence was observed between 220-302 GPa and complete melting occurs by 355 GPa. Furthermore, our observation of the lower coordination bcc structure in shocked gold is in marked contrast with theoretical predictions and the reported observation of the hexagonal-close-packed structure under static compression.

Structural transformations including melting and recrystallization during shock compression and release of germanium up to 45 GPa

Journal Article Renganathan, P. ; Turneaure, Stefan J. ; Sharma, Surinder M. ; ... - Physical Review B

Solid-solid and solid-liquid transformations were examined in Ge(100), using in situ x-ray diffraction measurements during uniaxial strain compression and release. For final stresses above 15.7 GPa, the Ge transformed to a highly textured tetragonal β-Sn phase. At 31.5 GPa and above, Ge transformed to the molten phase. Full stress release (uniaxial strain) from the β-Sn phase, from the melt boundary, and from the completely molten phase, resulted in reversion to an untextured cubic diamond (cd) phase. These findings demonstrate that the cd to β-Sn phase change is reversible, and that recrystallization from the liquid phase occurs on nanosecond timescales duringmore » release.« less

Measurements of the sound velocity of shock-compressed liquid silica to 1100 GPa

Journal Article McCoy, Chad August ; Gregor, Michelle C. ; Polsin, Danae N. ; ... - Journal of Applied Physics

The sound velocity in a shocked material provides information about its off-Hugoniot behavior of a material at high pressures. This information can be used to extend the knowledge gained in Hugoniot experiments and to model the re-shock and release behavior. Silica is one of the most important materials for equation of state studies because of its prevalence in the earth’s interior and the well-defined properties of α-quartz. This paper presents sound velocity measurements of amorphous fused silica over the range 200 to 1100 GPa using laser-driven shocks and an α- quartz standard. These measurements demonstrate the technique proposed by Fratanduonomore »« less

Ultrafast X-Ray Diffraction Studies of the Phase Transitions and Equation of State of Scandium Shock Compressed to 82 GPa

Journal Article Briggs, R. ; Gorman, M. G. ; Coleman, A. L. ; ... - Physical Review Letters

Using x-ray diffraction at the Linac Coherent Light Source x-ray free-electron laser, we have determined simultaneously and self-consistently the phase transitions and equation of state (EOS) of the lightest transition metal, scandium, under shock compression. On compression scandium undergoes a structural phase transition between 32 and 35 GPa to the same bcc structure seen at high temperatures at ambient pressures, and then a further transition at 46 GPa to the incommensurate host-guest polymorph found above 21 GPa in static compression at room temperature. Furthermore, shock melting of the host-guest phase is observed between 53 and 72 GPa with the disappearancemore »« less
