Effect of electropulsing on anisotropy behaviour of cold-rolled commercially pure titanium sheet WANG Zhong-jin(王忠金), SONG Hui(宋 辉) School of Materials Science and Engineering, Harbin Institute...; Abstract: The specimens cut from the cold-rolled pure titanium sheet at 0?, 45? and 90? to the rolling direction were treated by high......
Effect of dopant content on microstructure and properties of Si-Al-K doped molybdenum LI Da-cheng(李大成)1, ZHOU Zhang-jian(周张健)2, PU Chun-yang(卜春阳)1 1. Technology Center, Jinduicheng Molybdenum... properties and microstructure of molybdenum powder, sintering product and fabricated wires were studied. The molybdenum powder was produced firstly by reduction of molybdenum oxide which is doped......
Induction plasma spheroidization of tungsten and molybdenum powders JIANG Xian-Liang (蒋显亮)1, M.Boulos2 1. Institute of Surface and Coatings Technology, School of Materials Science and Engineering...; Abstract: The melting, evaporation and oxidation behaviors as well as the solidification phenomena of tungsten and molybdenum......
, China) Abstract: The type 250 open-train mill, by controlled rolling on the specifications for each 55 mm TA2 pure titanium billet rolled into d18 mm bar. The results show that the temperature control..., while maintaining good ductility increases by 18.3%. In addition, through controlling the temperature of the rolling process, the transverse and longitudinal structure of pure titanium bars trends......
prepared on the surface of Gd using the magnetron sputtering technique to improve its corrosion resistance. The corrosion behaviors for the pure Gd and Gd with Al coating in distilled water were studied using the mass loss and electrochemical performance. As a result, pure Gd without coating shows a certain amount of surface cracks under water flow conditions, whereas the polygonal Al coating......
