Journal ArticleDOI
Atomistic insights into the deformation mechanism of a CoCrNi medium entropy alloy under nanoindentation
TL;DR: In this article, the authors investigate the nucleation and evolution of dislocations in CoCrNi MEA during nanoindentation and analyze the effects of composition inhomogeneity and temperature on the defect behavior.
Journal ArticleDOI
A synchrotron study of defect and strain inhomogeneity in laser-assisted three-dimensionally-printed Ni-based superalloy
Yao Li,Dan Qian,Jiawei Xue,Jingchun Wan,Anfeng Zhang,Nobumichi Tamura,Zhongxiao Song,Kai Chen +7 more
TL;DR: In this paper, X-ray microdiffraction was employed to investigate the inhomogeneous distribution of defect and residual strain in the transitional region between the dendritic and stray grains in a laser-assisted 3D printed Ni-based superalloy.
Journal ArticleDOI
Ta@Ag Porous Array with High Stability and Biocompatibility for SERS Sensing of Bacteria.
Dongzhen Chen,Dongzhen Chen,Pan Ning,Zhang Yu,Jing Jinyu,Zhang Meng,Zhang Liang,Huang Jian,He Xinhai,Fu Tao,Zhongxiao Song,Guangyu He,Dan Qian,Xiaodong Zhu +13 more
TL;DR: This work provides a promising strategy to fabricate corrosion-resistant and biocompatible bimetallic Ta@Ag film with porous array, availing for the SERS sensing of microbial cell.
Journal ArticleDOI
A synchrotron study of microstructure gradient in laser additively formed epitaxial Ni-based superalloy
Jiawei Xue,Anfeng Zhang,Yao Li,Dan Qian,Jingchun Wan,Baolu Qi,Nobumichi Tamura,Zhongxiao Song,Kai Chen +8 more
TL;DR: It is shown that a disorientation gradient caused by a high density of geometrically necessary dislocations and resultant subgrains exists in the interfacial region between the epitaxial and stray grains, creating a potential relationship of stray grain formation and defect accumulation.
Journal ArticleDOI
Statistical study of ductility-dip cracking induced plastic deformation in polycrystalline laser 3D printed Ni-based superalloy.
TL;DR: A statistical study of the cracking behavior as a function of crystal orientation in a laser 3D-printed DL125L Ni-based superalloy polycrystal is investigated here using the synchrotron X-ray microdiffraction.
