Active research is ongoing that investigates the properties of matter under extreme pressure.
Such condensed matter is found inside planets at millions of atmospheres and thousands of …

The structure of molecules, particularly the dynamic changes in structure, plays an essential
role in understanding physical and chemical phenomena. Time-resolved (TR) scattering …

Abstract The transition from Hall-Petch (HP) to inverse Hall-Petch (IHP) behaviors
associated with grain size reduction has been recognized for over two decades. However …

We examine the effect of grain size on the dynamic failure of tantalum during laser-shock
compression and release and identify a significant effect of grain size on spall strength …

Ultrafast photoinduced melting provides an essential platform for studying nonequilibrium
phase transitions by linking the kinetics of electron dynamics to ionic motions. Knowledge of …

Materials subjected to dynamic environments experience a complex and wide range of
stress, strain, and strain-rate conditions. To have confidence in material models, an …

Understanding the deformation behavior of metallic materials at high strain rates requires
the characterization of plasticity contributors, such as twins, phase transformed regions, and …

The SPring-8 Ångstrom Compact free-electron LAser (SACLA) began parallel operation of
three beamlines (BL1–3) in autumn 2017 to increase the user beam time of the X-ray free …

Solid-state material at high pressure is prevalent throughout the Universe, and an
understanding of the structure of matter under such extreme conditions, gleaned from x-ray …

Shock compression of iron microstructures above a threshold stress results in a α BCC→ ε
HCP transformation, and the propagation of the release wave brings the metal back to the α …
