Abstract
Hydrogen solubilities have been measured for a series of Pd-Fe alloys in the temperature range from 393 to 523 K. From these equilibrium data the standard partial thermodynamic parameters at infinite dilution of H, ÎHH° and ÎSH° have been obtained and the former becomes less negative, and the latter more negative, with increase of XFe. H diffusion parameters have been determined in the Pd-Fe alloys (393-523 K). DH decreases and ED increases with XFe while the pre-exponential factors DH° do not change significantly. The dependence of DH and ED on H content have been determined for several of the Pd-Fe alloys and the former decreases and the latter increases with the H contents.
