Popis:	The temperature dependence of the equilibrium between m ethane-hydrogen gas mixtures of varying composition and carbon dissolved in bcc iron has been investigated. The data obtained have been analyzed to give values of the partial enthalpy and excess entropy of carbon in ferrite. The results have been discussed and compared to other investigations of the thermodynamic properties of the C-bcc-Fe system. From this investigation the partial excess entropy of the carbon is 6.56k, the partial enthalpy with respect to a solute atom at rest in a vacuum is −144.06 kcal per mole and the corresponding relative partial enthalpy is 23.34 kcal per mole at 1000°K.
