in catalytic reactions, such as selective oxidation of H2S into elemental sulfur and selective hydrogenation of nitrobenzene into aniline[10]. In comparison with other Ni-based catalysts, Ni-B amorphous alloy... elsewhere[13-14]. TEM observation was performed on a Hitachi H600 electron microscope. The Ni loading and bulk compositions of amorphous alloy were analyzed by inductively coupled plasma (ICP). The total......
June 2010 Abstract: The effect of the cooling slope on the structure of Zr-based metallic glass matrix composites was investigated by changing the cooling slope. The synthesis of bulk metallic glass... crystals formed in-situ during solidification could improve the ductility of Zr-based bulk metallic glasses[4-7]. The ductility improvement of such composites has been reported to arise from the pinning......
-based amorphous alloy and its corresponding crystalline counterpart are both lower than those of the Ti-based amorphous alloy in the 1 mol/L H2SO4 solution. In the 3.5% NaCl solution,Zr-based... the view of corrosion thermodynamics. For the Zr-based amorphous alloy, the passivation is observed at the beginning of anodic polarization. The passive film generated in the passivating process......
