Journal ArticleDOI
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
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
Damage-tolerant nanotwinned metals with nanovoids under radiation environments
Y. Chen,Kaiyuan Yu,Yuchen Liu,Shuai Shao,Haiyan Wang,Marquis A. Kirk,Jian Wang,Jian Wang,Xuan Zhang +8 more
TL;DR: This study shows that by using in situ heavy ion irradiation in a transmission electron microscope, pre-introduced nanovoids in nanotwinned Cu efficiently absorb radiation-induced defects accompanied by gradual elimination of nanovoid, enhancing radiation tolerance of Cu.
Journal ArticleDOI
Stacking fault and partial dislocation dominated strengthening mechanisms in highly textured Cu/Co multilayers
TL;DR: In this paper, the interfaces and mechanical properties of sputtered, highly (1 − 0) and textured Cu/Co multilayers are investigated. But the authors focus on the case where each layer is a few nanometers in thickness.
