摘要：
The interaction of the MoSi2-type intermetallic compounds Zr2Pd, Hf2Pd and Hf2Cu with hydrogen at pressures up to 2000 atm has been investigated. Absorption and desorption isotherms were measured at 293 K. For each system the formation of two hydride phases was established: tetragonal A2BH(approximately 3) and orthorhombic A2BH5.5-6. The volume expansions for these phases were 8%-10% and 21%-25% respectively. The thermal desorption of hydrogen from these phases was also studied.
