| 英文摘要 | h-2 permeation hysteresis has been observed during cycling of a 3 mu m thick supported pdcu membrane with similar to 50 atom % pd through the fcc/bcc (face-centered cubic/body-centered cubic) miscibility gap between 723 and 873 k. structural investigations after annealing of membrane fragments under h-2 at 823 k reveal retardation of the fcc(h) -> bcc(h) transition, which is attributed to the occurrence of metastable hydrogenated fee pdcu(h) phases. the h-2 flux at 0.1 mpa h-2 pressure difference in the well-annealed bcc single phase regime below 723 k can be described by j(h2) = (1.3 +/- 0.2) mol.m(-2).s(-1) exp[(-11.1 +/- 0.6) kj.mol(-1)/(rt)] and that in the fcc single phase regime above 873 k by j(h2) = (7 +/- 2) mol.m(-2).s(-1) exp[(-30.3 +/- 2.5) kj.mol(-1)/(rt)]. |
