“…Contrarily to the present study, our previous results of charge density distributions of titanium and zirconium hydrogen solid solutions [6,7] indicated an obvious decline of metal-metal bonding due to hydrogen addition, which caused the decrease in their elastic moduli and hardness. However, the elastic moduli and the hardness of yttrium hydrogen solid solution [22] were increased by hydrogen addition as well as the niobium hydrogen solid solution. Therefore, the interstitial hydrogen effect appears to depend on the group of periodic table (␣Y: 3A; ␣Ti, ␣Zr: 4A; ␣Nb: 5A) rather than on crystal structures (␣Ti, ␣Y, ␣Zr: hcp; ␣Nb: bcc).…”

Some characteristics of niobium hydrogen solid solution (hydrogen content, C H = 0.00-3.14 at.% H) were investigated in order to reveal the influence of hydrogen on the characteristics of niobium. The lattice parameter, the elastic moduli and the Vickers hardness of the niobium hydrogen solid solution were found to increase with increasing the hydrogen content. In addition to this experimental work, the electronic structure of the niobium hydrogen solid solution was evaluated by a first principle molecular orbital calculation. Finally, the mechanical properties of niobium hydrogen solid solution were discussed in terms of the calculation results.
