Abstract
The equilibrium solubility of hydrogen in Ta1-xAlx alloys (x=0, 1, 1.6, 2.4 and 3.2 atom % Al) was measured in the temperature range of 673 K to 873 K and hydrogen pressure range of 64 kPa to 115 kPa. The solubility decreases with increasing aluminium content at all temperatures and pressures investigated. From the equilibrium solubility data, partial molar free energy, enthalpy and entropy of solution of hydrogen were calculated. The relative partial molar enthalpy of hydrogen was found to increase with increasing Al content whereas the change in entropy was very small.
