✦ Synopsis

Simulation of phase transitions in the IMCehydrogen systems in the frames of perturbation theory provides accurate description of main characteristics of the phase diagrams in the wide range of hydrogen pressures. The data obtained for thermodynamic parameters of the aeb transitions gives a possibility to describe hydrogen solubility in TiMn 1.5 at the pressures up to 600 atm; the parameters of the critical point of the aeb equilibriums are also obtained. The proposed calculation scheme uses no fitting parameters or empirical correlations and leans upon atomic characteristics of the hydrogen subsystem and metallic matrix which are physically meaningful.
