The experimental determination of critical stresses for yielding and plastic flow is of upmost
importance for the understanding of the atomic-scale mechanical behaviors of nanoscale …

The Cantor high-entropy alloy (HEA) of CrMnFeCoNi is a solid solution with a face-centered
cubic structure. While plastic deformation in this alloy is usually dominated by dislocation …

Nanoscale small-volume metallic materials typically exhibit high strengths but often suffer
from a lack of tensile ductility due to undesirable premature failure. Here, we report unusual …

Ultrahigh surface-to-volume ratio in nanoscale materials, could dramatically facilitate mass
transport, leading to surface-mediated diffusion similar to Coble-type creep in polycrystalline …

Friction and wear are detrimental to functionality and reduce the service life of products with
mechanical elements. Here, we unveil the atomic-scale friction of a single tungsten asperity …

Low‐dimensional nanometals have significant applications in sensors, catalysis, data
storage and batteries, attributed to their unique mechanical, optical, magnetic, and electrical …

The development of xenon plasma focused ion-beam (Xe+ PFIB) milling technique enables
site-specific sample preparation with milling rates several times larger than the conventional …

A 5-fold twin is usually observed in nanostructured metals after mechanical tests and/or
annealing treatment. However, the formation mechanism of a 5-fold twin has not been fully …

Deformation twinning serves as an important mode of plastic dissipation processes in
nanoscale body-centered cubic (BCC) metals, but its origin and spatio-temporal features are …

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 …
