Thermodynamic behavior of dilute palladium-hydrogen solid solutions

C Labes, RB McLellan - Acta Metallurgica, 1978 - Elsevier
Temperature-composition isobars in the palladium-hydrogen system have been measured
at a series of seven different pressures chosen such that the resulting data could be
analyzed to provide the thermodynamic functions of the dissolved hydrogen atoms at
concentrations below 10− 2 atom fraction. Some indication has been found that the partial
thermodynamic functions are composition dependent. Since single crystals were used, this
effect is not due to the presence of grain boundaries. Both the partial excess entropy and …
