摘要(中)

本研究利用鑄造法結合退火熱處理製備高純度Mg17Al12合金，再利用球磨法製備出Mg17Al12+X wt.% Ni (X=0，10，20)合金，並透過充分活化與PCI測試，以研究該合金之吸放氫性質，期望藉由Ni的添加，以催化Mg17Al12合金，降低合金之吸放氫溫度並改善其吸放氫動力學。
　　由活化測試與吸放氫速率測試得知，將Ni添加至Mg17Al12中有助於提升合金氫化時之氫化百分比與吸氫速率，並降低吸氫溫度。在PCI氫化測試中，含Ni之Mg17Al12合金其氫化曲線具有三個氫化平台;由XRD結果證實，經過吸放氫反應後，含Ni之Mg17Al12合金組成已轉變為Mg17Al12、純Mg、Al3Ni及Al3Ni2，其中僅Mg17Al12與純Mg參與氫化反應，因而可推測第一平台為純Mg之氫化平台，第二平台為Mg17Al12轉變為氫化物MgH2及β相(Mg2Al3)，第三平台為β相轉變為MgH2及純Al，純Mg在Mg17Al12之催化下，吸氫動力學亦獲得大幅改善。

摘要(英)

Mg17Al12 alloy was prepared by melting method followed by annealing ,and then ball-milled with Ni for 3 hours to obtain Mg17Al12- X wt.% Ni (X=0，10，20) composite. XRD results showed that no new phases formed during ball milling ,all of the diffraction peaks correspond to Mg17Al2 and Ni. In the activation test, Mg17Al12-20 wt.% Ni composite showed the most rapid absorption rate and highest hydrogenation fraction, followed by Mg17Al12-10 wt.% Ni and pure Mg17Al12 , showed that Ni addition is useful to improve the hydrogenation properties of Mg17Al12 alloy. The hydrogenation reaction of Mg17Al12-Ni composite had been clarified by PCI and XRD, after cycles of hydriding/dehydriding, the composition of composite will changed from (Mg17Al12+Ni) to (Mg17Al12+Al3Ni+ Al3Ni2+Mg), led the hydrogenation reaction to proceed in 3 stage. This behavior is clearly visible from multi- plateaux of PCI curves.
