Abstract
⺠ZrFe2âxNix (x = 0.2, 0.4, 0.6, and 0.8) can accumulate up to 1.7-1.8 wt.% H2 at 295 K. ⺠H2 desorption pressures at 295 K decreased from 325 (x = 0) to 115 atm (x = 0.8). ⺠Isomer shifts (IS) remain constant with Ni content. ⺠Absorption of H2 results in increase in IS and hyperfine fields for all samples. ⺠Hydride decomposition process involves formation of intermediate hydride phase.
