Surface modification of spherical LiNi1/3Co1/3Mn1/3O2 with Al2O3 using heterogeneous nucleation process YANG Zhi(杨 志), LI Xin-hai(李新海), WANG Zhi-xing(王志兴), ZHU Yong-jun(朱勇军) School..., spherical LiNi1/3Co1/3Mn1/3O2 was coated with Al2O3 by using heterogeneous nucleation process, and the physical and electrochemical properties were studied. The SEM images show that there is a uniform......
Investigation of the Heterogeneous Nucleation on Fractal SurfacesMeng Wang , Ying Zhang, Haoyong Zheng, Xin Lin and Weidong Huang State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi an 710072, China摘 要:Classical theory of heterogeneous nucleation has been developed with an implied hypothesis of smooth substrate......
for grain structure formation based on the Monte Carlo method was carried out, and the frequency of heterogeneous nucleation in the alloy was evaluated by producing similar structure with the experimental one. The frequency of heterogeneous nucleation was expressed as a probabilistic function with an exponential form of undercooling that determines the probability of nucleation event in the simulation......
Effect of Substrate Surface Microstructure on Heterogeneous Nucleation BehaviorYing Zhang, Meng Wang, Xin Lin and Weidong Huang State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi an 710072, China摘 要:The heterogeneous nucleation behaviors of NH4Cl crystal on a rough chilling surface of aluminum immerged......

Effect of Ultrasound on Heterogeneous Nucleation in TIG Welding of Al–Li AlloyQi-Hao Chen,San-Bao Lin,Chun-Li Yang,Cheng-Lei Fan,Hong-Liang GeState Key Laboratory of Advanced Welding and Joining,Harbin Institute of Technology摘 要:The effect of ultrasound on heterogeneous nucleation in a tungsten inert gas(TIG) weld pool of 2195 Al–Li alloy has been......
Al8Fe4Nd phase was found shorter and the nucleation rate higher than those ofα-Al. The results indicate the nucleation of Al8Fe4Nd phase is heterogeneous and thedispersoids of Al8Fe4Nd form as primary...NUCLEATION BEHAVIOR OF Al8Fe4Nd PHASE IN RAPIDLY SOLIDIFIED AI-Fe-V-Si-Nd ALLOY H.Pang1,M.G.Zeng3,J.N.Deng3,Z.H.Jin1 (1.S henyang National Laboratory for Material Science, Institute of Metal......
structure, and the disregistry between Mg phases and AlN along (0001)Mg//(0001)AlN is 3.04%, which is very effective for heterogeneous nucleation. Key words: Mg alloy; Mg3N2; inoculation; heterogeneous... constitutional supercooling. The suitable nucleation substrates are required in the melt to stimulate a high nucleation frequency[15]. Heterogeneous nucleus of α-Mg was found in this work. According......

as the heterogeneous nucleation sites for dynamic recrystallization during the extrusion due to the crystallography matching relationship. Extrusion deformation leads to dynamic recrystallization, which results in the grain refinement and uniform distribution. The as-extruded Mg-9Li-5Sn alloy possesses the lowest grain size of 45.9 μm. Key words: Mg-9Li alloys; Sn; microstructure; heterogeneous nucleation 1......
