Nanocrystalline (nc) materials can be defined as solids with grain sizes in the range of 1–
100 nm. Contrary to coarse-grained metals, which become more difficult to twin with …

The aim of this Tutorial is to help new researchers understand how to perform molecular
dynamics (MD) simulations of the shock response of materials and to provide a brief …

In this work, molecular dynamics simulations are conducted to investigate the shock
responses and corresponding deformation mechanisms in single crystalline (SC) and …

We observe that a nanostructured metal can be hardened by annealing and softened when
subsequently deformed, which is in contrast to the typical behavior of a metal …

High-velocity microparticle impacts are relevant to many fields, from space exploration to
additive manufacturing, and can be used to help understand the physical and chemical …

The deformation behavior of nanocrystalline Ni–W alloys is evaluated by nanoindentation
techniques for grain sizes of 3–150nm, spanning both the range of classical Hall–Petch …

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

Despite its fundamental importance for a broad range of applications, little is understood
about the behaviour of metals during the initial phase of shock compression. Here, we …

Atomically ordered bimetal interfaces typically develop in near-equilibrium epitaxial growth
(bottom-up processing) of nanolayered composite films and have been considered …

In superhard materials research, two topics are of central focus. One is to understand
hardness microscopically and to establish hardness models with atomic parameters, which …
