Microstructure and properties of AZ31 magnesium alloy with rapid solidification ZHAO Hong-liang(赵红亮), GUAN Shao-kang(关绍康),ZHENG Fei-yan(郑飞燕), LI Qing-kui(李庆奎), WANG Li-guo(王利国) (College of Materials Engineering, Zhengzhou University, Zhengzhou 450002, China) Abstract: Rapidly solidified (RS) AZ31 magnesium alloy ribbons were made using melt spinning technique. The results show that its......
J. Cent. South Univ. Technol. (2009) 16: 0242-0246 DOI: 10.1007/s11771-009-0041-3 Recovery of copper sulfate after treating As-containing wastewater by precipitation method ZHENG Ya-jie(郑雅杰... As-containing wastewater till pH value was 6. Green copper arsenite was prepared after copper sulfate was added into the neutralized wastewater when the molar ratio of Cu to As was 2?1 and pH value......
Wrinkling behavior of magnesium alloy tube in warm hydroforming TANG Ze-jun(汤泽军), LIU Gang(刘 钢), HE Zhu-bin(何祝斌), YUAN Shi-jian(苑世剑) School of Materials Science and Engineering, Harbin Institute... occur and affect the forming results. Wrinkling behavior of an AZ31B magnesium alloy tube was experimentally investigated with different loading paths at different temperatures. Features of wrinkles......
: Magnesium oxysulfate (MgSO4·5Mg(OH)2·2H2O) flake powders with an average diameter of 2 μm and a thickness of 0.052 μm were prepared using magnesium sulfate and sodium hydroxide as raw... and small particle size [7, 16]. Some researchers have reported their work on the synthesis of magnesium oxysulfate whiskers. GAO et al [17] used magnesium chloride, ammonia and magnesium sulfate as raw......

Reheating microstructure of refined AZ91D magnesium alloy in semi-solid state JIANG Ju-fu(姜巨福), LUO Shou-jing(罗守靖) (School of Materials Science and Engineering, Harbin Institute of Technology.... With increasing equivalent strain, the average grain size decreases. This demonstrates that reheating material extruded by ECAE technology is a good method to prepare AZ91D magnesium alloy semi-solid billets. Key......
Twinning during hot compression of ZK30+0.3Yb magnesium alloy YE Cheng-wu(叶呈武), LIU Zhi-yi(刘志义),ZHANG Kun(张 坤), ZHENG Qing-chun(郑青春) (School of Materials Science and Engineering, Central South University, Changsha 410083, China) Abstract: The twinning process of ZK30+0.3Yb magnesium alloy was studied. The results show that twinning occurs at the initial stage of deformation......
