| 摘 要： | 采用机械合金化方法由Ｍｇ，Ｎｉ和Ｃｕ单质粉末以及添加第四组元粉末按选定比例合成ＭｇＮｉＣｕ和ＭｇＮｉＣｕ－Ｍ５％贮氢材料，着重研究了分别添加不同的第四组元Ａｌ，Ｍｎ，Ｔｉ元素对不同球磨时间后ＭｇＮｉＣｕ合金贮氢性能的影响。结果表明，添加第四组元都不同程度地改善了ＭｇＮｉＣｕ俣金的初始活化条件；添加Ｍｎ能降低ＭｇＮｉＣｕ合金的吸放氢平台，显著改善其吸放氢动力学性质；添加Ｔｉ提高了ＭｇＮｉＣｕ合金的最

| Abstract: | From ixed Mg,Ni,Cu element powders and the fourth addition element powder at a determined ratio,MgNiCu and MgNiCu-5wt%M hydrogen storage alloys were made by mechanical alloying.The paper studies how each the fourth addition element Al,Mn or Ti influences the hydrogen storage characteristics of MgNiCu alloys and results show that all the fourth elements could improve the initial activation condition of MgNiCu alloys to a varying degree Mn addition lowers hydriding and dehydriding plateaux and remarkably improves hydriding and dehydriding kinetics of MgNiCu alloys,Ti addition increases the maximum storage capactities and improves hydriding and dehydriding kinetics of MgNiCu alloys,and Al addition does not nearly improve hydrogen storage characteristics of MgNiCu alloys. |
