Mechanism map for nucleation and growth of helium bubbles in metals
Kazunori Morishita,R. Sugano +1 more
TL;DR: In this paper, the total free energy of a system containing helium bubbles and point defects (vacancies, helium and self-interstitial atoms) was evaluated and activation barrier for forming a helium bubble was derived, where the effect of helium on helium bubble formation was clearly shown.

Helium effects on microstructural evolution in tempered martensitic steels: In situ helium implanter studies in HFIR
TL;DR: In this article, microstructural evolutions in tempered martensitic steels (TMS) under neutron-irradiation, at fusion relevant He/dpa ratios and dpa rates, were characterized using a novel in situ He-implanter technique.

Theoretical basis for unified analysis of experimental data and design of swelling-resistant alloys☆
Louis K. Mansur,Eal H. Lee +1 more
TL;DR: In this paper, the theory of radiation-induced swelling is reviewed and concepts central to the understanding of experimental data and the control of swelling by alloy design are discussed, and approaches to alloy design for swelling resistance are recommended.

The effects of helium implantation on microstructural evolution in an austenitic alloy
Roger E. Stoller,G.R. Odette +1 more
TL;DR: In this article, a model austenitic alloy (Fe-17Cr-16.7Ni-2.5Mo) was implanted with 10 to 50 appm helium at room temperature and subsequently annealed at temperatures between 600 and 900°C.

A dual ion irradiation study of helium–dpa interactions on cavity evolution in tempered martensitic steels and nanostructured ferritic alloys
TL;DR: In this paper, the cavity evolutions in a normalized and tempered martensitic steel (TMS) and two nanostructured ferritic alloys (NFA) under Fe3+ and He+ dual ion beam irradiations (DII) at 500 and 650°C were characterized.

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.
