Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …

Atomistic simulations are a powerful complement to experimental probes for understanding
the nanoscale processes associated with the effects of hydrogen (H) on plasticity and …

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 …

In fusion reactor environment, helium bubble acts as a crucial inducement to the
performance degradation of plasma facing tungsten, leading to irradiation hardening and …

In this work, we calculate the local slip resistances (LSRs) in equal-molar MoNbTi multi-
principal element alloy via molecular static simulations. We consider dislocations of either …

The interaction between glissile dislocations and precipitates within a continuum is
responsible for marked increases in material strength. Due to their desirable engineering …

Radiation damage introduces a wide range of defects in structural materials depending on
the irradiation conditions. Irradiation-induced loops are known to lead to dislocation …

The aim of the present study is to extend the knowledge about the formation and thermal
stability of vacancy-type defects in tungsten under neutron irradiation, thereby mimicking the …

In this work, we have performed neutron irradiation and sub-sequent microstructural and
micro-hardness measurements on a series of tungsten grades. The neutron irradiation was …

The stress-driven motion of dislocations in crystalline solids, and thus the ensuing plastic
deformation process, is greatly influenced by the presence or absence of various pointlike …
