Shock Compression of Diamond Crystal
Two shock wave experiments employing Lau• technique. The normal axis to the sample inclined mirrors have been carried out to surface of both crystals were very close to each determine the Hugoniot elastic limit (HEL), final other and inclined 15.4 ñ 0.6 ø from <111>, or 29.6 shock state at 191 and 217 GPa, and the post-shock ñ 0.6 ø from <110> in approximately the (110) state of diamond crystal...
متن کاملShock Wave Compression of NaCl Single Crystals observed by Flash-X-Ray Diffraction
Flash-x-ray-diffraction patterns (FXD) with an exposure time of 4 ns of XaCl single crystals compressed bv plane shock waves are obtained a t pressures of about 30 kbar. From the diffraction patterns the compression is determined and compared with Hugoniot data. During shock load the lattice shows an uniaxial compression. While in case of measurements a t the free surface an observation time of...
متن کاملShock Compression of Single - Crystal Forsterite
Dynamic compression results are reported for single-crystal forsteritc loaded along the orthorhombic a and c axes to pressures from 130 to 165 GPa. Hugoniot states for the two axes are well described by a single curve offset to densities 0.15-0.20 g/cm 3 lower than earlier data for single-crystal forsteritc shocked along the b axis above 100 GPa. Earlier data of Syono et al. [ 1981a] show margi...
متن کاملMorphological Characterization of Combustion Deposited Diamond Crystals and Films
Single crystals and polycrystalline diamond films of several thicknesses were deposited using oxygen/acetylene combustion flame technique. The substrate used was pure polycrystalline molybdenum subjected to mechanical polishing. Quality and microstructural characteristic of diamond produced were investigated using X-Ray diffraction, Raman Spectroscopy, Scanning and Transmission Electron Microsc...
متن کاملInelastic response of silicon to shock compression
The elastic and inelastic response of [001] oriented silicon to laser compression has been a topic of considerable discussion for well over a decade, yet there has been little progress in understanding the basic behaviour of this apparently simple material. We present experimental x-ray diffraction data showing complex elastic strain profiles in laser compressed samples on nanosecond timescales...
