Dilatation on membrane V-1 alloy in hydrogen and deuterium atmosphere

Experimental data on dilatation on the V-1 alloy in hydrogen and deuterium atmosphere in the temperature range from 20 to 400 deg C and pressures from 0.2 to 4.1 MPa are presented. The excessive chemical potential of hydrogen isotope atoms dissolved in the given alloy is calculated. It permits to work out p-n-T diagrams for H-alloy, D-alloy systems in the field of thermodynamic parameters studied and to propagate then outside the limits for the range of measurement. Evaluation of interaction energy of hydrogen isotope atoms dissolved in the alloy lattice is given
