| 摘 要： | 研究了以V取代TiCr基储氢合金中的部分Cr对合金的吸氢平台压力、储氢容量以及储氢性能的影响.X射线衍射分析表明,合金的相组成随着合金中V含量的增加由单一的Laves相经由两相混合共存逐渐转变为单一的体心立方相;压力-温度-组成测试结果表明:V取代TiC1.8合金中的部分Cr可以有效降低合金的吸氢平台压力,提高合金的最大储氢量,同时合金吸氢反应的焓变也有很大的增加.

| Abstract: | To decrease the hydrogen absorbing plateau pressure and increase the hydrogen storage capacity of TiCr based alloy, chromium was partially substituted by vanadium. The dependence of hydrogen storage capacity on vanadium content was investigated. X-ray diffraction results show that alloy phase composition changes from single Laves phase to single body centered cubic phase with increasing vanadium content. Partial substitution of vanadium for chromium can decrease the hydrogen absorbing plateau pressure effectively. Both the maximum hydrogen absorption content and the enthalpy changes of hydrogen absorption increase with increasing vanadium content. |
