借助Ｘ射线衍射及透射电镜研究了ＭｍＮｉ(５－ｘ)（Ｃｏ，ＡＩ，Ｍｎ）ｘ／Ｍｇ混合粉末在高能球磨过程中的相交及其结构变化，证实高能球磨过程中ＭｍＮｉ(５－ｘ)（Ｃｏ,Ａｌ,Ｍｎ）ｘ与Ｍｇ之间发生了固态反应，并最终形成了纳米相复合结构．通过精确测定点阵常数和用Ｍｉｅｄｅｍａ方法估算反应的生成热，给出了可能的固态反应的反应式吸氢特性测定表明球磨制备的纳米相复合储氢合金有较好的性能通过对球磨后再退火的样品进行分析，进一步研究了所获得纳米相复合结构稳定性及其相交
The intercrossed and structural changes of MmNi (5-x) (Co, Al, Mn) x / Mg mixed powders during high energy ball milling were investigated by X-ray diffraction and transmission electron microscopy. (Co, Al, Mn) x and Mg solid state reaction occurred between, and eventually formed a nano-phase composite structure. By measuring the lattice constant accurately and using Miedema method to estimate the heat of reaction, the possible hydrogen absorption characteristics of the solid state reaction are given. The results show that the nanocomposite hydrogen storage alloy prepared by ball milling has better performance. Annealed samples for further analysis of the stability of the nanocomposite structure obtained and their intersection
