Pressure-composition (p-c) isotherms of the TiCrMn-H2(D2) system were measured over a wide temperature and pressure range (up to 1000 atm H2/D2) which included the super-critical range (above TC). The macroscopic thermodynamic parameters of the system and their isotope effects were evaluated. Also, hysteresis phenomenon between absorption and desorption isotherms were obtained as a function of temperature for the two hydrogen isotopes. The experimental p-c isotherms were compared to model calculated ones derived by simplified statistical thermodynamic treatments. From this comparison microscopic energy-related parameters were evaluated. These parameters included the average hydrogen-lattice interaction, the pairwise nearest-neighbor hydrogen-hydrogen interaction and the average vibrational frequency of H(D) at the interstitial sites.
