Abstract
The crystal structures, the lattice parameters and the characteristics of hydrogen storage at 303K has been investigated in the ternary alloys of 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 dependant on the composition ratio of Ti/Cr, showing their maximum values at the Ti/Cr ratio of about 0.75. It was also found that the lattice parameters of the alloys increased linearly with an increase of the Ti/Cr ratio. The differences in affinities to hydrogen and lattice parameters of pure metal states of the three elements have been adopted in oder to explain the Ti/Cr ratio dependance of the lattice parameter and hydrogen storage capacity of the alloys.
