In this paper, we report a formation mechanism of 1/2〈 111〉 interstitial dislocation loops via
the collapse of C15 clusters in bulk tungsten. The interstitial atoms formed C15 clusters in …

We investigated the influence of hydrogen (H) on the stability and mobility of small vacancy
clusters in tungsten (W) using the first-principles calculations. It is found that the presence of …

Single crystal W is offered for Physics understanding of irradiation induced defects and their
annealing as its structure is well defined and it is almost defect free. W (1 0 0) single crystal …

Simulations of neutron damage under fusion energy conditions must capture the effects of
transmutation, both in terms of accurate chemical inventory buildup as well as the physics of …

Mechanical responses of tungsten (W) and its alloys are strongly controlled by the properties
of 1/2< 111> screw dislocations. Rhenium (Re), as a typical alloying and transmutation …

Tungsten is widely used as a material capable of withstanding extreme operating conditions
and is one of the candidates for use in fusion and Generation IV fission reactors. Atomistic …

In this work, 3-point bending tests and micro-hardness measurements were performed on
pure tungsten irradiated with high-energy protons and spallation neutrons in a target of the …

In this paper, we present a transmission electron microscopy study of three tungsten grades
subjected to neutron irradiation and post-irradiation annealing. The irradiation was …

Dislocation loops finely disperse in bulk W are generally visible to the transition electron
microscopy (TEM) after irradiation. In the absence of strong interactions, these loops would …

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 …
