Ion beams are indispensible for understanding radiation effects in materials, enabling
access to conditions challenging to perform with neutrons. However, ion irradiations can …

We investigate the structure and mobility of single self-interstitial atom and vacancy defects
in body-centered-cubic transition metals forming groups 5B (vanadium, niobium, and …

Abstract Changes in microstructure and mechanical properties of nuclear materials are
governed by the kinetics of defects produced by irradiation. The population of vacancies …

We report a detailed ab initio study of the stability and migration of self-interstitial atoms
(SIAs) and di-interstitials (di-SIAs) in α-Fe. The⟨ 110⟩ dumbbell is confirmed to be the most …

Dislocations are ubiquitous linear defects and are responsible for many of the properties of
crystalline materials. Studies on the glide process of dislocations in bulk materials have …

The performance of four recent semi-empirical interatomic potentials for iron, developed or
used within the FP6 Perfect Project, is evaluated by comparing them between themselves …

This paper is the first of three that overview the main mechanisms that drive the
microstructure evolution in Fe alloys under irradiation. It focuses on pure α-Fe and compiles …

The migration of point defects, for example, crystal lattice vacancies and self-interstitial
atoms (SIAs), typically occurs through three-dimensional random walk in crystalline solids …

Tensile specimens of pure Fe were neutron irradiated at 50–70° C in three fission reactors to
displacement dose levels of 0.0001–0.79 displacements per atom (dpa). Irradiated …

The interaction between dislocations and point defects is key to deformation processes and
microstructural evolution of structural materials. In this work, we compute the lifetime of point …
