Many methods used to produce nanocrystalline (NC) materials leave behind non-
equilibrium grain boundaries (GBs) containing excess free volume and higher energy than …

In alloys under irradiation many mechanisms exist that couple phase instability to cavity
swelling. These are compounded with the more familiar mechanisms associated with point …

Kanthal APMT is a promising FeCrAl-based alloy for accident-tolerant fuel cladding because
of its excellent high-temperature oxidation resistance. In this study, powder metallurgy …

The unusual mechanical and radiation properties found in concentrated solid–solution
alloys (CSAs) make them promising candidate materials in nuclear applications. In this work …

In the field of radiation damage of crystalline solids, new highly-concentrated alloys (HCAs)
are now considered to be suitable candidate materials for next generation fission/fusion …

Oxide dispersion strengthened (ODS) alloys containing high-density nano-oxides show
excellent mechanical properties and irradiation tolerance. However, ODS alloys are often …

This work presents a multiscale and multiphysics framework to investigate the radiation-
induced damage in nano-crystalline materials. The framework combines two methodologies …

ABSTRACT A combined experimental and computational evaluation of damage
accumulation in ion-irradiated Ni, NiFe, and NiFeCoCr is presented. A suppressed damage …

Radiation-induced defects cause severe degradation of materials properties during
irradiation that can ultimately cause the material to fail. Consequences of these defects …

Irradiation creates excess point defects in materials (vacancies and self-interstitial atoms),
which can be eliminated by mutual recombination, clustering, or annihilation of preexisting …
