, 0.1, 0.2, 0.3, 0.4) alloys were prepared by melt-spinning technology. The spun ribbons with a continuous length, a thickness of about 30 μm and a width of about 25 mm were obtained. The microstructures...) capability, for which the increased glass forming ability by Co substitution is mainly responsible. Key words: Mg2Ni-type alloy; melt-spinning; substituting Ni with Co; electrochemical hydrogen......

investigated.The results indicated that the non-Ca Cu5 phases in the alloy became tinier and more dispersive after annealing or melt-spinning compared to those of the as-cast one.But in the spun then annealed...; cast then annealed < as-spun,and the change of plateau pressure showed the opposite trend with that of the cell volume.The plateau could be flattened after melt-spinning or annealing,and the spun......
-deformed magnets can be prepared by single-roller melt-spinning. In order to prepare well-structured ribbons, the model of temperature field for single-roller melt-spinning process was constructed in this work. The heat conduction in this process was simplified as one dimensional heat conduction problem. It was shown by modeling that, the temperature field in the melt-spinning before solidification......

by vacuum induction melting followed by melt-spinning. It is found that the electrochemical capacity of alloys at different temperature depends upon the compositions and preparation methods. The electrochemical capacity of alloys increases at higher temperature (40 ~ 80 ℃ )and decreases at lower temperature ( - 30 ~ 0 ℃ ) with an increasing cobalt content. With an increasing temperature,melt-spinning......
evolution in these alloys was discussed. An amorphous alloy composition was found in this system and a melt-spinning amorphous alloy was produced in this composition. Through DSC analysis, the amorphous alloy......
