    摘要:

    采用X射線衍射(XRD)法分析了TiCr1.8-xVx儲(chǔ)氫合金氫化并吸氫后的相組成，首次采用熱重-差熱掃描-質(zhì)譜(TG-DSC-MS)聯(lián)用技術(shù)對(duì)合金隨溫度變化時(shí)的放氫特性及所釋放氫的狀態(tài)進(jìn)行了研究。根據(jù)不同升溫速率條件下，合金放氫的DSC測試計(jì)算了放氫反應(yīng)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.
