Amorphous materials are metastable solids with only short-range order at the atomic scale,
which results from local intermolecular chemical bonding. The lack of long-range order …

Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

Small-scale mechanical testing on irradiated materials is gaining popularity in the nuclear
materials community due to the fact that mechanical property changes can be evaluated …

Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors
after high dose energetic particle irradiation. In the past decades, extensive studies have …

Metallic glasses boast high strength, but their low ductility has been a major concern. Here,
taking a structural perspective and citing selected examples, we advocate purposely …

The workability and ductility of metals usually degrade with exposure to irradiation, hence
the phrase “radiation damage”. Here, we found that helium (He) radiation can actually …

High energy particles introduce severe radiation damage in metallic materials, such as Ag.
Here we report on the study on twin boundary (TB) affected zone in irradiated nanotwinned …

Tailoring nanoscale defect structures for desirable deformation behaviors is crucial to
designing and optimizing the mechanical properties of alloys. Distinguishing from the …

SRIM-like codes have limitations in describing general 3D geometries, for modeling
radiation displacements and damage in nanostructured materials. A universal …

We investigate the mechanical behavior and atomic-level structure of glassy Zr-Ni-Al nano-
tensile specimens with widths between 75 and 215 nm. We focus our studies on two …
