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 …

Scanning transmission electron microscopy (STEM) is widely used for imaging, diffraction,
and spectroscopy of materials down to atomic resolution. Recent advances in detector …

The need for enhanced radiation-tolerant materials for advanced nuclear energy designs
has resulted in a growing number of investigations that have explored the effect of grain …

Metals subjected to irradiation environments undergo microstructural evolution and
concomitant degradation, yet the nanoscale mechanisms for such evolution remain elusive …

Grain growth and phase stability of a nanocrystalline face-centered cubic (fcc) Ni 0.2 Fe 0.2
Co 0.2 Cr 0.2 Cu 0.2 high-entropy alloy (HEA), either thermally-or irradiation-induced, are …

Nanostructured metals are a promising class of radiation-tolerant materials. A large volume
fraction of grain boundaries (GBs) can provide plenty of sinks for radiation damage, and …
