Phase Composition and Hydrogen Desorption Characteristics of Hydrided TiCr1.8-xVx Alloys

摘要:

采用X射线衍射(XRD)法分析了TiCr1.8-xVx储氢合金氢化并吸氢后的相组成，首次采用热重-差热扫描-质谱(TG-DSC-MS)联用技术对合金随温度变化时的放氢特性及所释放氢的状态进行了研究。根据不同升温速率条件下，合金放氢的DSC测试计算了放氢反应的活化能。

Abstract:

The phase compositions of hydrided TiCr1.8-xVx hydrogen storage alloys were examined by X-ray diffraction (XRD) and thermal gravity-differential scanning calorimetry-mass spectrometry (TG-DSC-MS) firstly to study the dependence of hydrogen desorption characteristics with temperature, and the states of released hydrogen were inspected by the mass spectrometry. The active energy of hydrogen desorption was calculated at different heating rates by the differential scanning calorimetry tests.
