Journal ArticleDOI
Size-dependent fracture of silicon nanoparticles during lithiation.
TL;DR: In this article, a strong size dependence of fracture was discovered; that is, there exists a critical particle diameter of ∼150 nm, below which the particles neither cracked nor fractured upon first lithiation, and above which they initially formed surface cracks and then fractured due to lithiation-induced swelling.
Journal ArticleDOI
Additively manufactured hierarchical stainless steels with high strength and ductility
Y. Morris Wang,Thomas Voisin,Joseph T. McKeown,Jianchao Ye,Nicholas P. Calta,Zan Li,Zhi Zeng,Yin Zhang,Wen Chen,Tien T. Roehling,Ryan T. Ott,Melissa K. Santala,Philip J. Depond,Manyalibo J. Matthews,Alex V. Hamza,Ting Zhu +15 more
TL;DR: The potential of additive manufacturing to create alloys with unique microstructures and high performance for structural applications is demonstrated, with austenitic 316L stainless steels additively manufactured via a laser powder-bed-fusion technique exhibiting a combination of yield strength and tensile ductility that surpasses that of conventional 316L steels.
Journal ArticleDOI
Tuning element distribution, structure and properties by composition in high-entropy alloys.
Qingqing Ding,Yin Zhang,Xiao Chen,Xiaoqian Fu,Dengke Chen,Sijing Chen,Lin Gu,Fei Wei,Hongbin Bei,Yanfei Gao,Yanfei Gao,Minru Wen,Jixue Li,Ze Zhang,Ting Zhu,Robert O. Ritchie,Robert O. Ritchie,Qian Yu +17 more
TL;DR: Atomic-resolution chemical mapping reveals deformation mechanisms in the CrFeCoNiPd alloy that are promoted by pronounced fluctuations in composition and an increase in stacking-fault energy, leading to higher yield strength without compromising strain hardening and tensile ductility.
Journal ArticleDOI
Anisotropic Swelling and Fracture of Silicon Nanowires during Lithiation
Xiao Hua Liu,He Zheng,He Zheng,Li Zhong,Shan Huang,Khim Karki,Liqiang Zhang,Liqiang Zhang,Yang Liu,Akihiro Kushima,Wentao Liang,Jiangwei Wang,Jeong Hyun Cho,Eric Epstein,Shadi A. Dayeh,S. Tom Picraux,Ting Zhu,Ju Li,Ju Li,John P. Sullivan,John Cumings,Chunsheng Wang,Scott X. Mao,Zhizhen Ye,Sulin Zhang,Jian Yu Huang +25 more
TL;DR: This anisotropic swelling results in lithiated Si nanowires with a remarkable dumbbell-shaped cross section, which develops due to plastic flow and an ensuing necking instability that is induced by the tensile hoop stress buildup in the lithiated shell.
Journal ArticleDOI
Ultra-strength materials
TL;DR: In this paper, an overview of the principal deformation mechanisms of ultra-strength materials is presented, and the fundamental defect processes that initiate and sustain plastic flow and fracture are described, as well as the mechanics and physics of both displacive and diffusive mechanisms.
