Thermodynamic assessment of the U–Mo–Al system

Thermodynamic properties of uranium in gallium–aluminium based alloys

“…Solubility of uranium in liquid Al at 913e1143 K [14] agrees well with the liquidus line in UeAl phase diagram [16]. Of the ternary systems containing uranium and aluminium, UeAleMo is, perhaps, the best studied owing to its importance for predicting the behaviour of UeMo fuel in aluminium matrix [17,18].…”

Calphad thermodynamic description of some binary systems involving U

“…5c) in equilibrium with this phase is better described by our version. These phases have a Mo solubility too large in the description by Zhang et al [7] with respect to Dwight [31] and Gomozov and Lyutina [32] experimental results (Fig. 5d).…”

“…For the other equilibria, the present description presents a better agreement with experiments. The solubility of Mo in c-U described by Zhang et al [7] is too large. The miscibility gap between the two bcc phases surprisingly expands with increasing temperature (Fig.…”

“…Fig. 5b-d present dashed lines corresponding to calculations performed using the recent description published by Zhang et al [7] as well as different available experimental data. The agreement of both calculated phase diagram to experiments is good for the equilibria involving the liquid phase.…”

“…For each system, the available experimental data are summarized and compared with calculations using the assessed thermodynamic description. For the systems with W and Mo, other Calphad descriptions [6,7] have been published after the actual completion of our work and are also compared.…”
