Abstract
Pressure-composition (P-C) isotherm and X-ray diffraction measurements on Zr(Mn{sub 1-y}Nb{sub y}){sub x} (x=0.97-2.91, y=0-0.208; 26 charges) have been carried out. The equilibrium pressure decreases and the lattice parameter increases with increasing Nb addition. The hydrogen capacity of non-stoichiometric Zr(Mn{sub 1-y}Nb{sub y}){sub x} (hypo-Zr) is nearly proportional to the total number of Zr2Mn2, ZrNbMn2, Zr2MnNb and ZrMn2Nb interstices. Both vertical stroke {Delta}H{sub A} vertical stroke and vertical stroke {Delta}H{sub D} vertical stroke increase with increasing lattice parameter, with the former showing a clearer dependence than the latter. {Delta}S{sub A} shows a weak dependence on the lattice parameter, but {Delta}S{sub D} shows no dependence at all. Both {Delta}H{sub A}/{Delta}S{sub A} and {Delta}H{sub D}/{Delta}S{sub D} display a strong dependence on the lattice parameters. The degree of slope of the plateau in the P-C isotherm is nearly proportional to vertical stroke {Delta}H vertical stroke {Delta}{sub c}(2{theta}), where {Delta}{sub c}(2{theta}) is the corrected halfwidth of the X-ray diffraction profile.
