Grain size has a profound effect on the mechanical response of metals. Molecular dynamics
continues to expand its range from a handful of atoms to grain sizes up to 50 nm, albeit …

Shock loading takes materials from ambient conditions to extreme conditions of temperature
and nonhydrostatic stress on picosecond timescales. In molecular materials the fast loading …

Nanostructured high-entropy alloys (HEAs) with excellent properties have recently attracted
extensive attention from both academia and industry in recent years. However, as a …

Mountains on rapidly rotating neutron stars efficiently radiate gravitational waves. The
maximum possible size of these mountains depends on the breaking strain of the neutron …

The ultrafast evolution of microstructure is key to understanding high-pressure and strain-
rate phenomena. However, the visualization of lattice dynamics at scales commensurate …

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 …

Materials respond to shock in many ways such as plastic flow in metals and amorphization
in ceramics. It is very challenging to characterize the deformation mechanisms of ceramics …

In situ x-ray diffraction has been used to characterize the structural modifications of tantalum
samples under intense laser irradiation, up to 135 GPa in a diamond anvil cell. Melting data …

Aluminium typically deforms via full dislocations due to its high stacking fault energy.
Twinning in aluminium, although difficult, may occur at low temperature and high strain rate …

Shockwave interactions with a material's microstructure localizes energy into hotspots,
which act as nucleation sites for complex processes such as phase transformations and …
