Void-interface wetting to crossing transition owing to bubble to void transformation
Shijian Zheng,Shijian Zheng,J.C. Pang,J.C. Pang,Lixin Yang,Wenfan Yang,Wenfan Yang,Yangtao Zhou,Yongqiang Wang,Fuxing Yin,Xiuliang Ma,Xiuliang Ma +11 more
TL;DR: In this paper, a cavity-interface interaction is studied in high-strength, radiation-tolerant nanocomposites, where bubbles near the Cu-Nb interface in Nb could be absorbed by Cu voids wetting the interface due to the high system energy difference produced by the huge pressure difference between the bubbles and voids and high mobility of bubbles, and no bubble-denuded zone forms owing to fast Brownian motion of bubbles.
Modeling of Helium Bubble Nucleation and Growth in Neutron Irradiated RAFM Steels
TL;DR: In this article, a physically based model using Rate Theory is developed to describe nucleation and growth of helium bubbles in neutron irradiated reduced activation Ferritic/Martensitic (RAFM) steels.

Hierarchical-interface design for stable helium storage and structural evolution in homogeneous nano-multilayered Al1.5CoCrFeNi high entropy alloy films
Guo-jiang Pu,Qiran Li,Yihan Wang,Jia Feng Li,Sheng Chen,Kun Zhang,Chia-Chieh Yang,Zhijun Wang,Liwei Lin,Ding Ren,Zongbiao Ye,Bin Liu,Bo Liu +12 more
TL;DR: In this paper , hierarchical interfaces and nanometer grain boundaries (GBs) were synchronously designed inside the homogeneous Al1.5CoCrFeNi high entropy alloy (HEA) nano-multilayered films, in which each lamellae was composed of nano-crystals to construct helium ion radiation-tolerant materials used for future advanced nuclear-energy system.

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.

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.
