| dc.description.abstract | 本研究以真空電弧熔煉法製備TixFe(1-y)My(M=Mn,Ni)系列合金，藉由微結構觀察與儲氫特性測量，探討不同Ti/Fe比與合金元素Mn、Ni對於儲氫性質之影響。結果顯示提升Ti/Fe比可改善合金活化特性與儲氫量，Ti1.1Fe的有效放氫量為1.54 wt%，是Ti-Fe二元合金中有效放氫量最佳之組成。當Mn的添加不超過12wt%時，有助於提升Ti1.1Fe(1-x)Mnx合金活化特性與有效放氫量。其Ti1.1Fe0.75Mn0.25合金有效放氫量為1.54 wt%。Ti1.1Fe0.75Mn0.25合金隨Ni含量增加，合金中各項儲氫性質皆下降。以活化特性、動力學性質、有效放氫量與遲滯行為各項儲氫特性作比較，Ti1.1Fe0.75Mn0.25為此一系列合金最佳成分。

| dc.description.abstract | This research plans to utilize arc-melted method to prepare TixFe(1-y)My (M=Mn,Ni) alloys,and then studies the effect of the Ti/Fe ratio and element M(M=Mn,Ni) substitution on Ti-Fe alloys of hydrogen storage properties with different microstructure.It was found that increasing of Ti/Fe ratio could improve activation characteristics and effective hydrogen content.The best effective hydrogen storage capacity of Ti-Fe binary is 1.54wt% and its composition is Ti1.1Fe.The activation characteristics and hydrogen desorption capacity was improved when Mn contained less than 12 wt%. The best effective hydrogen storage capacity of Ti1.1Fe0.75Mn0.25 alloy is 1.54 wt%.The hydrogenation properties got worse with increasing of Ni content in Ti1.1Fe0.75Mn0.25 alloy. In consideration of activation properties, kinetics, effective capacity and hysteresis characteristics, Ti1.1Fe0.75Mn0.25 alloy is the best composition in this study.
