Abstract

The crystal structures, the lattice parameters and the characteristics of hydrogen storage at 303 K have been investigated in ternary alloys of the Ti-Cr-V system. All of these alloys, in the range of this study, have shown a BCC structure. The hydrogen storage capacities and the effective hydrogen storage capacities of the alloys were strongly dependent on the composition ratio of Ti/Cr, showing their maximum values at a Ti/Cr ratio of about 0.75. It was also found that the lattice parameters of the alloys increased linearly with increasing Ti/Cr ratio. The differences in affinities to hydrogen and the atomic radius of each element could explain the Ti/Cr ratio dependence of the lattice parameter and hydrogen storage capacity of the alloys.
