چکیده انگلیسی
The migration of hydrogen in fast cooled Pd-H alloys is investigated by electrical resistivity measurement around 50Â K. The disordered atoms of hydrogen are introduced by fast cooling from around 80Â K to around 20Â K. The disordered atoms are ordered by migration of the atoms during heating-up of the specimens with the constant rates. The resistivity is measured at the temperatures as done by Vajda et al. to compare our results with their results. The activation energy of migration of hydrogen is obtained from the kinetic analysis of the resistivity change due to the ordering using a so-called cross-cut method. The obtained value is compared with our previous results, which have been obtained with hydrogen disordered by quenching into liquid helium, isothermal annealing of the specimen and resistivity measurement in liquid helium. The present value is in fairly good agreement with the value obtained in the quenched case.
