Nanostructured metals and alloys possess ultrahigh strength but suffer from severe shear
instability (strain localization). Recent experiments have shown that the strength and strain …

A very broad distribution of microstructural length scales spanning few nm-to the μm-scale
has proven effective to achieve exceptional materials properties. Here, we fabricate a Cu/Nb …

The nucleation of lattice dislocations and interface sliding at bimetal interfaces are two
fundamental mechanisms of plasticity that are responsible for the mechanical responses of …

Chemical short-range order (CSRO), as a nanoscale atomic feature, has been found to
significantly alter material properties in various alloys. Here, we use Fe-Ni-Cr alloys to …

Amorphous intergranular films (AIFs) have been proven in experiments to improve the
damage tolerance of nanocrystalline materials. However, a quantitative study is still lacking …

Although nanostructures and oxide dispersion can reduce radiation-induced damage in
materials and enhance radiation tolerance, previous studies prove that MoS2 …

We developed a novel low-activation, ultrafine-grained W-Cr-V multicomponent alloy (MCA)
with excellent thermal stability and desirable high-temperature strength. The as-sintered W …

To investigate the reason for the reduction in damage resistance of In x Ga 1− x N with
increasing indium (In) content, we used molecular dynamics methods to simulate the …

A stacking fault tetrahedron (SFT) is a very common kind of defects in face-centered cubic
metals under irradiation environment. The grain boundary (GB) migration can effectively …

Atomic arrangements in the nanostructured grains and interfaces of thermally evaporated
Au/Cu multilayer thin films on polycrystalline Si substrate have been explored through …
