摘　　要：用双辊快淬工艺制备了纳米晶AB5型富镧稀土贮氢合金。对热处理后的合金进行X射线衍射和扫描电镜SEM分析，并测试合金的吸放氢等温平衡曲线PCT。结果表明，处理的合金晶粒尺寸〈50nm，该合金具有良好的吸放氢动力学性能。The nanocrystalline AB5 type rich-lanthanum rare earth hydrogen storage alloys were prepared by double-roller rapid quenching. Grains structure of alloys thermo-treated were determed by XRD and SEM, and P-C-T curves were measured. Results indicated that grains sizes of the alloy were lower than 50nm and dynamics performances of hydrogen absorption and desorption of alloys were perfect.
