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.
Journal ArticleDOI
Mechanical properties of highly textured Cu/Ni multilayers
TL;DR: In this paper, the synthesis of highly textured Cu/Ni multilayers with individual layer thicknesses, h, varying from 1 to 200nm, was reported. And the influence of layer interfaces as well as twin interfaces on strengthening mechanisms of multi-layer and the formation of twins in Ni in multi-ayers were discussed.
Journal ArticleDOI
Removal of stacking-fault tetrahedra by twin boundaries in nanotwinned metals
Kaiyuan Yu,Daniel Charles Bufford,Cheng Sun,Yue Liu,Hui Wang,Marquis A. Kirk,Matthew Li,Xinghang Zhang +7 more
TL;DR: This work presents an alternative solution to remove stacking-fault tetrahedra discovered during room temperature, in situ Kr ion irradiation of epitaxial nanotwinned Ag with an average twin spacing of ~8 nm and reveals a new phenomenon: radiation-induced frequent migration of coherent and incoherent twin boundaries.
Journal ArticleDOI
Radiation damage in helium ion irradiated nanocrystalline Fe
TL;DR: In this article, a magnetron sputtering technique was used for the deposition of Fe films with an average columnar grain size varying from 49 to 96nm. But the results showed that the resulting compressive stress in Fe films is a combined consequence of He bubble induced hardening and radiation induced compressive stresses.
Journal ArticleDOI
Microstructure and strengthening mechanisms in Cu/Fe multilayers
TL;DR: In this article, the growth orientation relationship between Cu and Fe at the interfaces was determined to be of the Kurdjumov-Sachs and Nishiyama-Wasserman type.
