The extraordinary work hardening ability and fracture toughness of the face-centered cubic
(fcc) high-entropy alloys render them ideal candidates for many structural applications. Here …

It is a new beginning for innovative fundamental and applied science in nanocrystalline
materials. Many of the processing and consolidation challenges that have haunted …

There has been a challenge for many decades to understand how heterogeneities influence
the behavior of materials under shock loading, eventually leading to spall formation and …

Symmetric and asymmetric tilt grain boundaries in Cu and Al were generated using
molecular statics energy minimization in a classical molecular dynamics code with in-plane …

Shock compression and spallation damage of a face-center cubic phase high-entropy alloy
(HEA) Al 0.1 CoCrFeNi were investigated via plate impact experiments along with free …

The growth of an isolated spherical void at and near a grain boundary or a triple junction is
studied by means of full-field crystal plasticity simulations with explicit representation of the …

Damage in metallic materials usually originates at grain boundaries where deformation
leads to local strain incompatibility and stress concentration. Characteristics of a grain …

Additive manufacturing has the potential to be used for repair of high-value parts, but the
strength and integrity of such repaired parts, especially under dynamic loading, in still …

It is generally recognized that single crystals exhibit orientation-dependent elastic and
plastic responses. However, it is less known how the dynamic tensile, or spall, strength …

We present a non-destructive in-situ measurement of three-dimensional (3D) microstructure
evolution of 99.995% pure polycrystalline copper during tensile loading using synchrotron …
