The purpose of this work dealt with the measurements of the equilibrium pressure of deuterium and with the determination of the thermodynamic properties of deuterium in V, Nb and Ta. The P-T-X relationships were established for these three systems using the modified Sieverts’ apparatus in the range of 0.1∼104 Pa, 0.1∼40 atomic percent of deuterium and the temperature range of 423∼773 K.<BR>The equilibrium pressure of deuterium and the relative partial molar quantities of deuterium are larger than that of hydrogen in the three systems. In the Nb-D system, the two phase region has been measured in the range of 19∼32 at%D, 2.3×10−1 Pa at an isotherm of 443 K. The isocomposition measurement was carried out in the two system, V-D, and Nb-D, and the two phase region for each system was estimated at temperatures below 393 K for V-D and 453 K for Nb-D, respectively. The partial phase diagram of each system was proposed on the basis of the results of the resistometric work. It is clear that the phase boundary of α⁄(α+β) in each of the Nb-D and Ta-D systems was located at a slightly higher temperature position than that of the Nb-H and Ta-H systems. However, in the system of V-D this was a reverse.
