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 …

Metals usually have three crystal structures: face-centered cubic (fcc), body-centered cubic
(bcc), and hexagonal-close packed (hcp) structures. Typically, metals exhibit only one of …

Ultrafast laser processing technology has offered a wide range of opportunities in
micro/nano fabrication and other fields such as nanotechnology, biotechnology, energy …

We present a combined experimental and computational investigation of the mechanical
properties of a CoCrFe 0.75 NiMo 0.3 Nb 0.125 (composition in molar ratio) high-entropy …

A clear understanding of the dynamic behavior of metals is critical for developing superior
structural materials as well as for improving material processing techniques such as cold …

Permanent structural changes in pure metals that are caused by plastic activity are normally
irreparable after unloading. Because of the lack of experimental evidence, it is unclear …

The ability to process metallic samples at the sub-micrometer scale raised the strength limits
of pure metals to the Giga Pascal (GPa) range. Here, we fabricated Mo nanoparticles with a …

As deformation rate increases, the thermally activated dislocation glide gives way to a
continuous glide of dislocations governed by their interactions with phonons. Understanding …

Over the past two decades, means allowing to probe experimentally the mechanical
behavior of materials specimens only a few micrometers or less in diameter have multiplied …

Nanosized metals usually exhibit ultrahigh strength but suffer from low homogeneous
plasticity. The origin of a strength–ductility trade-off has been well studied for pure metals …
