Refractory complex concentrated alloys, RCCAs, show great potential for ultrahigh-
temperature applications. High-temperature strength is one of the key requirements for …

Nanocrystalline materials have been proposed as superior radiation tolerant materials in
comparison to coarse grain counterparts. However, there is still a limited understanding …

The ability of high-entropy alloys to resist radiation damage is rooted in their compositional
complexity and associated high configurational entropy. In addition, grain boundaries within …

Energetic ions have been widely used to evaluate the irradiation tolerance of structural
materials for nuclear power applications and to modify material properties. It is important to …

Random solid solution alloys are a broad class of materials that are used across the entire
spectrum of engineering metals, whether as stand-alone materials (eg Al-5xxx alloys) or as …

Several advanced nuclear reactor designs promise efficiency and safety improvements over
the current reactor fleet but are limited by the current set of ASME code-qualified materials …

Defect evolution under irradiation is investigated in a set of single-phase concentrated solid
solution alloys (SP-CSAs) containing Ni with Co, Fe and/or Cr. We show that atomic …

Ever increasing energy needs have raised the demands for advanced fuels and cladding
materials that withstand the extreme radiation environments with improved accident …

Defect-driven diffusion of impurities is the major phenomenon leading to formation of
embrittling nanoscopic precipitates in irradiated reactor pressure vessel (RPV) steels …

Diffusion and mass transport are basic properties that control materials performance, such
as phase stability, solute decomposition and radiation tolerance. While understanding …
