| 摘 要： | 本文用X射线衍射和差热分析的方法测定了LaNi5-NdNi5,LaNi5-CeNi5两个赝二元系相图。用X射线衍射线宽化法测定了活化后LaNi5-NdNi5体系的样品晶粒尺寸的各向异性。考查了吸氢性能和第二相存在对LaNi5吸氢性能的影响。测定和计算了两个体系中样品的点阵常数、单胞体积、原了间距吸氢前后的变化。从结构的观点,解释了LaNi5-NdNi5体系中活化后样品晶粒尺寸各向异性的原因。用本实验的结果,解释了RmNi5(Rm代表混合稀土金属)的吸氢量和平台压力的差异。

| Abstract: | The phase diagrams of pseudo-binary systems LaNi5-NdNi5 and LaNi5-CeNi5, the aniso-tropy of grain sizes of actived LaNi5-NdNi5 samples, hydrogen absorption capacity and hydrogen desorption isotherms at 29℃ and influence of other phase on hydrogen absorption characteristics of LaNi5 have been investigated by means of X-ray diffraction and DTA, X-ray diffraction line broadening method, and second ways respectively.The variations of lattice parameters, unit cell volumes and atomic distances of actived and unactived samples were determined.The anisotropy of grain sizes of actived LaNi5-NdNi5 system, the difference of hydrogen absorption capacity and hydrogen absorption plateau pressures of RmNi5(Rm = misch-metal) were explained from structure viewpoint and our experimental results. |
