Statistical model and first-principles simulation on concentration of HenV cluster and He bubble formation in α-Fe and W
Yue-Lin Liu,Yang Yu,Zhenhong Dai +2 more
TL;DR: In this article, the stability of He and He n -vacancy (He n V) clusters in α-Fe and W was investigated using first-principles calculations.
Journal ArticleDOI
Molecular statics calculations of the biases and point defect capture volumes of small cavities
TL;DR: In this article, it is shown that cavities have an interstitial bias as well, particularly at small sizes, which can act as a nucleation barrier against void formation, and that these effects may have a serious effect on the coarse-grained kinetic methods used to evaluate long term microstructural evolution in irradiated metals, and a means of incorporating this data into those methods is suggested.

Computational design of solid-state interfaces using O-lattice theory: An application to mitigating helium-induced damage
TL;DR: In this paper, an approach for designing interfaces with pre-specified internal structure and functionality using O-lattice theory is presented, where an interface intended to mitigate helium (He)-induced damage by promoting precipitation of He into continuous linear channels is presented.

Voids in Irradiated Stainless Steel
C. Cawthorne,E. J. Fulton +1 more
TL;DR: In this paper, electron microscope examination by the thin foil technique has been carried out on samples of stainless steel irradiated in the Dounreay Fast Reactor, either in the form of cladding on experimental fuel elements or as specimens intended for mechanical property tests.

Void Swelling in Metals and Alloys Under Irradiation: An Assessment of the Theory
TL;DR: In this paper, the theory of swelling is reviewed in terms of basic concepts and simulation and impurity effects, and the basic theory employs the formalism of chemical reaction rates, e.g., voids, dislocations, etc.
Journal ArticleDOI
Experimental effects of helium on cavity formation during irradiation—a review
TL;DR: In this paper, a review of cavity formation and swelling in non-fissile materials during neutron irradiation and charged particle bombardments is presented, which is explainable in terms of cavity nucleation on submicroscopic critical size gas bubbles, and on the influence of the neutral sink strength of such bubbles.

An improved equation of state for inert gases at high pressures
I.R. Brearley,D.A. MacInnes +1 more
TL;DR: In this paper, a hard sphere equation of state is developed in order to describe inert gas behaviour at high temperatures and/or pressures, and the use of the hard sphere EOS in modelling fission gas behaviour during a thermal transient is shown to be a more robust estimator of the fissure gas pressure in bubbles than the reduced van der Waals EOS.

Fission-fusion correlations for swelling and microstructure in stainless steels: Effect of the helium to displacement per atom ratio
TL;DR: In this article, the effects of the helium to displacement per atom ratio on microstructural evolution, with emphasis on austenitic stainless steels, were analyzed to determine mechanistic trends and a model calibrated to the fission reactor data was used to extrapolate to fusion conditions.
