Abstract

We report direct lattice level measurements of plastic relaxation kinetics through time-resolved, in-situ Laue diffraction of shock-compressed single-crystal [001] Ta at pressures of 27-210 GPa. For a 50 GPa shock, a range of shear strains is observed extending up to the uniaxial limit for early data points (<0.6 ns) and the average shear strain relaxes to a near steady state over ~1 ns. For 80 and 125 GPa shocks, the measured shear strains are fully relaxed already at 200 ps, consistent with rapid relaxation associated with the predicted threshold for homogeneous nucleation of dislocations occurring at shock pressure ~65 GPa. The relaxation rate and shear stresses are used to estimate the dislocation density and these quantities are compared to the Livermore Multiscale Strength model as well as various molecular dynamics simulations.

Shock compression of organic polymers and proteins: Ultrafast structural relaxation dynamics and energy landscapes

Journal Article Kim, H ; Hambir, S A ; Dlott, D D - Journal of Physical Chemistry B: Materials, Surfaces, Interfaces, amp Biophysical

The response of organic polymers and proteins including poly(methyl methacrylate) and the protein bovine serum albumin (BSA) to a short duration 4.5 GPa shock pulse, termed a nanoshock, is studied using ultrafast coherent Raman spectroscopy (CARS) to monitor density-dependent vibrational frequency shifts of a dye molecule probe. In conventional shock compression experiments, a two-part response of PMMA to fast compression is usually explained with a phenomenological viscoelastic model. The molecular basis for this two-part response is discussed here using an energy landscape model to describe large-amplitude structural relaxation of shocked supercooled liquids. The polymers and the protein show an instantaneousmore »« less

Studies of dynamic properties of shock compressed single crystals by in situ dynamic x-ray diffraction and sample recovery

Technical Report Meyers, Marc A. ; Schneider, M. S. ; Jarmakani, H. ; ...

Laser compression provides pressures ranging from a few to hundreds of GPa at pulse durations of the order of nanoseconds or fractions thereof. The short duration ensures a rapid decay of the pulse and quenching of shocked sample in times that are orders of magnitude lower than in conventional explosively driven plate impact experiments. Systematic experiments carried out in specimens well suited for transmission electron microscopy characterization are revealing that laser compression, by virtue of a much more rapid cooling, enables the retention of a deformation structure closer to the one existing during shock. The smaller pulse length decreases themore »« less

Constitutive model used in computer simulation of time-resolved, shock-wave data

Conference Steinberg, D J

A constitutive model was designed for use with high-speed, hydrodynamic computer codes. The model, valid at high-deformation rates, accounts for pressure and temperature dependence of the yield strength and shear modulus, work hardening, pressure-dependent melting, Bauschinger and strain-rate effects, and spall. There are a minimum number of parameters needed to implement the model, and most can be determined without recourse to shock-wave data. At Lawrence Livermore National Laboratory, we assembled a library of these material properties for 44 metals, alloys, mixtures, and compounds. Shock and release data from plate-impact experiments for Be, U, Ta, Cu, 1100-0, and 6061-T6 al, withmore »« less
Transition of dislocation glide to shear transformation in shocked tantalum

Journal Article Hsiung, Luke L. ; Campbell, Geoffrey H. - MRS Advances

A TEM study of pure tantalum and tantalum-tungsten alloys explosively shocked at a peak pressure of 30 GPa (strain rate: ~1 x 10 ⁴ sec ^-1) is presented. While no ω (hexagonal) phase was found in shock-recovered pure Ta and Ta-5W that contain mainly a low-energy cellular dislocation structure, shock-induced ω phase was found to form in Ta-10W that contains evenly distributed dislocations with a stored dislocation density higher than 1 x 10 ¹² cm ^-2. The TEM results clearly reveal that shock-induced α (bcc) → ω (hexagonal) shear transformation occurs when dynamic recovery reactions which lead the formation low-energymore »« less

Influence of peak pressure and temperature on the structure/property response of shock-loaded Ta and Ta-10W

Journal Article Gray, III, G T ; Vecchio, K S - Metallurgical Transactions, A

The deformation behavior and substructure evolution of unalloyed-Ta and Ta-10W under quasistatic conditions have been compared to their respective responses when shock prestrained to 20 GPa at 25 C as well as to unalloyed-Ta shocked to 7 GPa at 25 C, 200 C, and 400 C. The reload yield behavior of shock-prestrained Ta and Ta-10W did not exhibit enhanced shock hardening when compared to their respective quasistatic stress-strain response at an equivalent strain level. In addition, the reload yield behavior of Ta shock prestrained to 7 GPa at 200 C or 400 C was found to exhibit increased hardening comparedmore »« less
