InP Bulk Crystals Grown from Various Stoichiometric Melt Sun Tongnian1,Zhao Zhengping2,Sun Niefeng3,Zhou Xiaolong1,Wu Xiang2,Mao Luhong3 (1.National Key Laboratory of ASIC, Hebei Semiconductor..., China) Abstract:InP crystal was grown from stoichiometric or non-stoichiometric melt, including P-rich and In-rich condition by the P-injection synthesis LEC method. Owing to the non-stoichiometric......

Study on the Free-Surface Flow of Silicon Melt in the CrucibleLi Yingchun;Wan Qun;Qin Fu General Research Institute for Non-ferrous Metals,Beijing,China摘 要:<正> The flowing of the free-surface-layer melt in the crucible has been studied by means of observing the movement ofthe mark particle on the free-surface of silicon melt.A new view......
Simulation of electromagnetic-flow fields in Mg melt under pulsed magnetic field WANG Bin(汪 彬), YANG Yuan-sheng(杨院生), MA Xiao-ping(马晓平), TONG Wen-hui(童文辉) Institute of Metal Research... and on the distribution of magnetic and flow fields were numerically studied. The pulsed magnetic field increases melt convection, which stirs and fractures the dendritic arms into pieces. These broken pieces......
of experiments were carried out to investigate permeability and ion diffusion properties of new-old concrete composite by measuring 6-hour coulomb charge and chloride diffusivity. The interrelation among transport properties of new-old composites, new, and old concretes was also discussed. Results indicate that the permeability and chloride diffusivity of new-old concrete composite system closely......
Microstructure Formation in Al-Bi-Co Immiscible Alloys Directionally Solidified with Different Melt Superheat TemperaturesJie He , Chengyao Xing, Jiuzhou Zhao and Lei Zhao Institute of Metal Research... with different melt superheat temperatures. The microstructure characterization and the quantitative metallographic analysis have been performed. The results indicated that the Bi-rich sphere size and cellular......
