| Abstract: | 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. |
