Most of the phase transformations modifying the microstructure, thereby the materials
properties, are controlled by the diffusion of atoms. The rate but also the selection of phase …

In this study, APT and TEM analyses were used to characterise two Zr-based alloys neutron-
irradiated to 13.7 dpa. The high spatial and chemical resolution of these techniques has …

Transition state calculation is a critical technique to understand and predict versatile
dynamical phenomena in solids. However, the transition state results obtained at 0 K are …

A nanoscale characterization study was carried out on SRA ZIRLO™ at various cycles,
aiming to highlight the effect of irradiation-induced alloying element (Sn, Nb, Fe) …

We have investigated microstructure and microchemistry of precipitates and dislocation
loops in high-burnup M5® using (scanning) transmission electron microscopy ((S) TEM) …

The effect of Sn on the formation of-component dislocation loops was investigated by the
combination of in situ ion irradiation and density functional theory calculations. The size of …

Surface, inner and interface damages of Cr coatings irradiated by 5 MeV protons were
characterized by XRD, SEM, TEM and nanoindentation in this work. After irradiation, a Cr 7 …

The presence of Al in the hexagonal close-packed (HCP) Al-Sc-Hf-Ti-Zr high-entropy-alloy
system was previously found to be a primary reason for partial D0 19 ordering. Since tracer …

Abstract The Zr (Fe, Cr) 2 second phase particles (SPPs) found in Zircaloy-2 and-4 are
known to amorphize and dissolve under irradiation. In the present work, their evolution has …

The diffusion of lanthanide fission products plays an important role in the growth of the fuel-
cladding chemical interaction (FCCI) region in metallic fuels. The use of a Zr interdiffusion …
