Constitutive relations for slip and deformation twinning behaviors of a number of metals,
including α-titanium, copper, α-iron, and tantalum materials, are described over a very large …

Four topics associated with constitutive equation descriptions of rate-dependent metal
plastic deformation behavior are reviewed in honor of previous research accomplished on …

Dynamic compression by multiple shocks is used to compress iron up to 560 GPa (5.6
Mbar), the highest solid-state pressure yet attained for iron in the laboratory. Extended x-ray …

Iron is a key constituent of planets and an important technological material. Here, we
combine in situ ultrafast x-ray diffraction with laser-induced shock compression experiments …

The recent discovery of thousands of planets outside our Solar System raises fundamental
questions about the variety of planetary types and their corresponding interior structures and …

Ramp compression along a low-temperature adiabat offers a unique avenue to explore the
physical properties of materials at the highest densities of their solid form, a region …

The paper is focused on investigation of the mechanisms and kinetics of plastic deformation
of alloys under high-rate loading (at the strain rates> 10 5 s− 1). To study alloy behavior …

A series of magnesium single crystals, from 0.2 to 3 mm thick, were shock loaded in
directions parallel and perpendicular to the c-axis of the hexagonal closed packed (hcp) …

Iron undergoes a bcc to close-packed structural phase transition under pressure, at around
13 GPa, as shown by diamond anvil and shock experiments. Atomistic simulations have …

Iron was ramp-compressed over timescales of 3≤ t (ns)≤ 300 to study the time-
dependence of the α→ ε (bcc→ hcp) phase transformation. Onset stresses (σ α→ ε) for the …
