Journal ArticleDOI
Development of Micro Selective Laser Melting: The State of the Art and Future Perspectives
TL;DR: In this paper, the state of the art of additive manufacturing (AM) at the micro-scale level is reviewed, including powder recoating, laser optics, and powder particle size.
Journal ArticleDOI
Separating plasticity-induced closure and residual stress contributions to fatigue crack retardation following an overload
TL;DR: In this paper, the authors investigated the role of crack closure and residual stress on crack retardation following an overload and concluded that the residual stress effect is relatively short-lived, whilst the closure effect that is dominant at low values of R causes longer range retardation.
Journal ArticleDOI
Recrystallization-based grain boundary engineering of 316L stainless steel produced via selective laser melting
Shubo Gao,Zhiheng Hu,Martial Duchamp,P.S. Sankara Rama Krishnan,Sravya Tekumalla,Xu Song,Matteo Seita +6 more
TL;DR: In this article, the authors explore a different GBE processing route that leverages TB multiplication during recrystallization of austenitic 316L stainless steel produced via selective laser melting (SLM).
Journal ArticleDOI
Advances in additive manufacturing process simulation: Residual stresses and distortion predictions in complex metallic components
Xu Song,Stefanie Feih,Wei Zhai,Chen-Nan Sun,Feng Li,Raj Maiti,Jun Wei,Yangzhan Yang,Victor Oancea,León Romano Brandt,Alexander M. Korsunsky +10 more
TL;DR: In this paper, the ABAQUS AM module is employed to simulate two important metal additive manufacturing processes: (a) Laser Direct Energy Deposition (LDED) and (b) Selective Laser Melting (SLM).
Journal ArticleDOI
Composite NASICON (Na3Zr2Si2PO12) Solid-State Electrolyte with Enhanced Na+ Ionic Conductivity: Effect of Liquid Phase Sintering.
Jin An Sam Oh,Jin An Sam Oh,Linchun He,Anna Plewa,Anna Plewa,Masato Morita,Yue Zhao,Tetsuo Sakamoto,Xu Song,Wei Zhai,Kaiyang Zeng,Li Lu +11 more
TL;DR: This study has achieved a highly ionic conductive NZSP only by facile addition of Na2SiO3 into the NZSP powder prior to sintering stage, which contributes to the increment of the bulk ion conductivity.
