On the one hand, Irradiation is everywhere and irradiation effect, especially the material
irradiation damage effect under strong irradiation field, is one of the key factors for the …

How displacement damage defects generate and evolve in materials irradiated by energetic
particles is a perennial topic in the field of nuclear materials. Here we experimentally reveal …

Tungsten-based materials are considered to be one of the most promising plasma-facing
materials, but there are still many problems in practical application. Plasma-facing materials …

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

We have systematically investigated the influence of carbon (C) impurity on the aggregation,
migration, and annihilation of neutron irradiation defects as well as the mechanical …

In this work, we have carried out a series of displacement cascade simulations in tungsten
(W), including seven different primary-knock-on atom (PKA) directions, and PKA energy …

Rhenium (Re), as a typical alloying and transmutation element in tungsten (W), can
significantly enhance the irradiation hardening, but its underlying mechanism remains to be …

Nuclear data, describing neutron reaction probabilities (cross sections) and decay
behaviour, are critical to the design and operation of fusion experiments and future fusion …

The plasticity of tungsten in low or medium temperature regimes is dominated by the screw
dislocation mobility, which is well known to exhibit a strong non-Schmid effect and loading …

Due to its great performance, tungsten (W) and W-based alloys have been considered as
the candidates for plasma-faced materials in future fusion reactors. However, the radiation …
