Flow behavior and microstructural evolution in nickel during hot deformationWen-Li Gao,Shi-Zhen Lai,Jie Teng,Zhen-Tao Du,Xue-Sheng Liu,Yao-Wei ChangCollege of Materials Science and Engineering, Hunan UniversityJinchuan Nickel and Cobalt Research and Engineering Institute,Jinchuan Group Nickel Alloy Co.Ltd.摘 要:The hot deformation behavior of pure nickel......
(as arrowhead notation) of nickel deposition and Ni-SiC deposition current may be a little larger than that of pure Ni deposition. In the range of -800--1 000 mV, the electric current gradually increases with increasing potential. The current of pure Ni deposition exceeds that of Ni-SiC deposition, which may reflect the influence of SiC particles on the nucleation and growth process of nickel electron......

Effect of Yttrium Implantation on Microstructure and Adhesive Property of Nickel Oxide Film靳惠明1,周小卫11. College of Mechanical Engineering, Yangzhou University摘 要:Isothermal and cyclic oxidation behaviors of pure and yttrium-implanted nickel were studied at 1000 ℃ in the air. Scanning electronic microscopy (SEM) and transmission electronic microscopy (TEM......
that when immersing solid Ni in liquid Zn saturated with Fe, the intermetallic compound layers consisted of γ and δ phases are formed on nickel substrate, which is the same as that in liquid pure zinc... by diffusion of nickel atom across a concentration boundary layer in liquid Zn saturated with Fe, and is different from a mixed control mechanism of nickel in liquid pure zinc. The participation of Γ2......
