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合金的初始活化条件;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合金的最大贮氢量，也改善了其吸放氢动力学性质;添加Al几乎不改变MgNiCu合金的贮氢性能。
MgNiCu and MgNiCu-M5% hydrogen storage materials were prepared by mechanical alloying method from Mg, Ni and Cu single-component powders and the fourth component powders with the selected proportions. The effects of adding different fourth component Al, Mn, Effect of Ti Element on Hydrogen Storage Properties of MgNiCu Alloy after Different Ball Milling. The results show that the addition of the fourth component improves the initial activation conditions of MgNiCu alloy to some extent. Adding Mn can decrease the hydrogen absorption and desorption platform of MgNiCu alloy and improve the kinetics of hydrogen absorption and desorption. Adding Ti improves the initial activation conditions of MgNiCu alloy The maximum hydrogen storage capacity also improved the kinetics of hydrogen absorption and desorption. Adding Al almost did not change the hydrogen storage capacity of MgNiCu alloy.
