“…Performing this experiment with a powder sample could hypothetically lead to incorrectly identifying the driven bcc {110} reflection as the hcp {100} plane. This would incorrectly yield a c/a ratio of 1.64 for the hcp phase, which is significantly higher than observed in either dynamic 59 or static 60 experiments, and could have misleading geophysical implications [61][62][63] .…”

In situ X-ray diffraction with advanced X-ray sources offers unique opportunities for investigating materials properties under extreme conditions such as shock-wave loading. Here, Singh's theory for deducing high-pressure density and strength from two-dimensional (2D) diffraction patterns is rigorously examined with large-scale molecular dynamics simulations of isothermal compression and shock-wave compression. Two representative solids are explored: nanocrystalline Ta and diamond. Analysis of simulated 2D X-ray diffraction patterns is compared against direct molecular dynamics simulation results. Singh's method is highly accurate for density measurement (within 1%) and reasonable for strength measurement (within 10%), and can be used for such measurements on nanocrystalline and polycrystalline solids under extreme conditions (e.g. in the megabar regime).
