Separation efficiency of alumina particles in Al melt under high frequency magnetic field GUO Qing-tao(郭庆涛)1, CAO Zhi-qiang(曹志强)2, ZHANG Zhong-tao(张忠涛)2, LI Ting-ju(李廷举)2, JIN Jun-ze(金俊泽)2, HONG... with diameters varying from 30 to 200 μm in aluminum melt were investigated. The experimental results show that the particle- accumulated layer is formed in the periphery of the solidified specimen......
. The distribution of Gd element in Mg-Li-Gd alloys indicates that Gd element mainly distributes at the grain boundaries of Mg-Li-Gd alloys. Key words: electrochemical codeposition; Mg-Li-Gd alloy; chloride melt...-AES, OM, SEM-EDS were used to characterize the Mg-Li-Gd alloys. Corrosion resistance of the alloy was investigated in sodium chloride solution. 2 Experimental The mixture of LiCl-KCl-MgCl2-Gd2O3......

SiC paper. The specimens without preheating were statically dipped into the molten aluminum liquid and held for different time. Then, the specimens were taken out from the melt and cooled in air to room... on the etched surfaces due to localized attack of aluminum melt. That is to say, those weak areas, such as defects inside material, grain boundaries and phase boundaries are prone to be eroded by molten......
