Defect-interface interactions
TL;DR: In this paper, the authors review the present understanding of defect-interface interactions in single-phase and two-phase metal and oxide nanocomposites, emphasizing how interface structure affects interactions with point, line, and planar defects.

Dose dependence of the microstructural evolution in neutron-irradiated austenitic stainless steel
TL;DR: In this paper, microstructural data on the evolution of the dislocation loop, cavity, and precipitate populations in neutron-irradiated austenitic stainless steels are reviewed in order to estimate the displacement damage levels needed to achieve the steady state condition.

Design of Radiation Tolerant Materials Via Interface Engineering
Weizhong Han,Michael J. Demkowicz,Nathan A. Mara,Engang Fu,Subhasis Sinha,Anthony D. Rollett,Yongqiang Wang,John S. Carpenter,Irene J. Beyerlein,Amit Misra +9 more
TL;DR: A novel interface engineering strategy is proposed to simultaneously achieve superior irradiation tolerance, high strength, and high thermal stability in bulk nanolayered composites of a model face- centered-cubic (Cu)/body-centered-cUBic (Nb) system.

Radiation damage in nanostructured materials
Xinghang Zhang,Khalid Hattar,Youxing Chen,Lin Shao,Jin Li,Cheng Sun,Kaiyuan Yu,Nan Li,Mitra L. Taheri,Haiyan Wang,Jian Wang,Michael Nastasi +11 more
TL;DR: In this paper, the authors summarized and analyzed the current understandings on the influence of various types of internal defect sinks on reduction of radiation damage in primarily nanostructured metallic materials, and partially on nanoceramic materials.

Effect of grain boundary character on sink efficiency
TL;DR: In this paper, the authors investigated the dependence of the width of void-denuded zones (VDZs) on grain boundary (GB) characters in Cu irradiated with He ions at elevated temperature.

Segregation of alloying elements to free surfaces during irradiation
Paul R. Okamoto,H. Wiedersich +1 more
TL;DR: In this article, an analysis of the segregation-induced strain field around the voids indicates that minor substitutional alloying elements with negative and positive size factors segregate towards and away from the void surface respectively.

Calculated Size Distributions for Gas Bubble Migration and Coalescence in Solids
TL;DR: In this article, a finite difference approach is used to predict the variation of the number of bubbles per unit volume as a function both of bubble size and of post-irradiation annealing time.
Journal ArticleDOI
Voids in irradiated metals. part i.
TL;DR: In this paper, the basic reason for void formation is preferential absorption of interstitials at dislocations, which depends on competition between alternative sinks for diffusing vacancies and inter-stitials.
