摘要：

A high performance apparatus for hydrogen analysis in metal has been constructed and applied to examine low hydrogen solubility in molybdenum. Hydrogen solubility in a molybdenum single crystal was measured at temperatures of 500 - 1000-degrees-C at a hydrogen pressure of 1.01 3 x 10(5) Pa. A linear relationship between the hydrogen solubility and reciprocal temperature was observed in the temperature range between 500 and 1000-degrees-C, providing an enthalpy of solution of 37.2 kJ/g-atom. The solubility data were analyzed by a solution model, and partial molar quantities of hydrogen were obtained.
