Bowman, Jr, R C

The relationships among hydride crystal structure, alloying, hydrogen interstitial site occupancy, and diffusion behavior have been explored in several ternary metal hydride phases where titanium is a major component. The specific hydrides being considered include: TiCuH/sub x/, TiFeH/sub x/, and TiCr/sub 2/H/sub x/. The temperature dependencies of proton relaxation times have been measured over accessible regions between 100 K and 570 K to characterize the hydrogen diffusion parameters. A wide diversity occurs with diffusion coefficients spanning several orders of magnitude. The roles of structure and hydrogen site occupancy on the diffusion mechanisms will be discussed.
