Thermodynamic study of the palladium-yttrium-hydrogen system

Equilibrium isobars for the ternary solid solution Pd-Y-H have been measured in the temperature range 625-1250 K and the composition range 0-13 at. % Y. The maximum H content was 1.5 at. %. The isobars were determined at six different pressures ranging from 1.01 x 103 to 1.01 x 105 N/m2. The resulting partial thermodynamic functions for H atoms in the solid solution are in good accord with the predictions of the cell model for such systems. (author)
