The process of void nucleation, growth, and coalescence is among the dominant ductile
failure modes in metallic alloys and can be transgranular as well as intergranular. In the …

The effects of neutron radiation on nickel-based alloys in thermal reactors are defying
predictions that were made based upon accelerated testing in fast reactors. As nickel-based …

Three ferritic/martensitic alloys were studied to understand the synergistic effect between
single ion beam (Fe 2+), dual ion beam (Fe 2++ He 2+ and Fe 2++ H+), and triple ion beam …

High-resolution electron backscatter diffraction (HR-EBSD) can provide an estimate of
elastic strains at a microscopic scale. Due to the need for high-quality Kikuchi patterns, HR …

Intergranular ductile fracture is a failure mode that may arise in many metallic alloys used in
industrial applications. It manifests as the successive nucleation, growth, and coalescence of …

He bubbles can exhibit different behaviors due to their different positions in the
nanocrystalline materials. Using molecular dynamics simulations, we study the dynamic …

So far, many theoretical and experimental studies have investigated the detrimental effect of
helium nanobubble on the mechanical properties of nuclear structural materials. In this …

This paper describes molecular dynamics simulations of fracture along a grain boundary
(GB) in nickel (Ni) decorated with helium (He)-filled bubbles. We find that the quantity …

Ductile fracture through growth and coalescence of intergranular cavities is a failure mode
observed experimentally in many metallic alloys used in industrial applications. Simulation …

Imaging nanoscale features using transmission electron microscopy is key to predicting and
assessing the mechanical behavior of structural materials in nuclear reactors. Analyzing …
