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 …

Self-ion irradiation of pure tungsten with 2 MeV W ions provides a way of simulating
microstructures generated by neutron irradiation in tungsten components of a fusion reactor …

Tungsten is considered to be used in the future fusion reactors as plasma-facing material. In
such extreme environments, defects are induced in materials that modify their macroscopic …

The thermal evolution of vacancies and vacancy clusters in tungsten (W) has been studied.
W (100) single crystals were irradiated with 200 keV hydrogen (H) ions to a low damage …

The evolution of Frenkel pairs has been studied experimentally and theoretically in tungsten,
a Body-Centered Cubic metal. We used positron annihilation spectroscopy to characterize …

Positron annihilation lifetime spectroscopy (PALS) was applied to study the annealing of
radiation-induced defects in polycrystalline tungsten (W) irradiated with 21.6 MeV protons at …

The influence of defects induced by plastic deformation of tungsten (W) on deuterium (D)
retention has been studied. Recrystallized W samples were subjected to tensile …

The identification of defects in neutron damaged materials is essential for elucidating the
correlation between the microstructure and the properties of a material. Positron annihilation …

The paper presents new knowledge on primary defect formation in tungsten (W) and iron
(Fe) irradiated by fission and high-energy neutrons at near-room temperature. Using a well …

The understanding of the neutron irradiation effects in tungsten is of significant importance
for its use as a plasma facing material in future fusion devices. In this study, cold rolled …
