Experimental re-determination and thermodynamic assessment of the erbium–zirconium system

Experimental study and thermodynamic description of the erbium–hydrogen–zirconium ternary system

“…6. Those obtained at the second step are in better agreement with the enthalpies deduced from the thermodynamic assessment of the system [8]. In spite of this result, it is still not clear which kind of relaxation best describes the actual thermodynamic properties.…”

“…The two binary systems Er-H and Er-Zr have been thermodynamically described only once in the literature [7,8] and both descriptions have been accepted. The choice made for the H-Zr system is justified hereunder.…”

“…A substitutional solution model has been used and no hydrogen solubility was considered [8]. It is, regardless, extremely low at the temperatures at which the liquid appears.…”

“…The end-members and interaction parameters are taken from the three papers [3,7,8] unless they have been modified as explained above. The values for the different end-members are summarized in Table 7.…”
