摘要：

The effects of nonmetal addition such as B, C, O, S and Se, on hydriding properties were investigated for Ti0.9Zr0.1Mn1.4Cr0.4V0.2 Laves phase alloys. It was found that for both as-cast and annealed samples, the addition of nonmetal elements such as S, Se and C greatly increases the plateau pressure, improves the plateau slope factor, and expands the hysteresis. The effect of increasing the plateau pressure was strongest for the S addition. These phenomena are possibly related to the appearance of manganese-rich minute particles as observed by scanning electron microscopy. The above effects pave the way for increasing the hydrogen storage capacity of the Ti-Mn Laves phase alloys.
