| Abstract |
Amorphous Ni-Zr alloys were produced by mechanical alloying of elemental powders and the hydrogen storage site in these alloys was predicted based on the experimental results of maximum hydrogen content per metal atom and those of atomic distribution functions obtained respectively from hydrogen absorption and X-ray diffraction experiments. Both results were applied to Harris model which is that hydrogen atoms occupy the interstitial sites in five types of A_(4-n)B_n(n=4, 3, 2, 1, 0) [where A(B) is a late(early) transition metal] tetrahedrons in the order of increasing site energies and explained well by this model. |
