“…Experimental phase diagram data [10,11,13,14], enthalpies of mixing of liquid alloys [16,18] and heat contents [20,21] were used in their optimization. Although the calculated results agreed well with most of the experimental data, the largest deviation of invariant reaction temperature was 28 K. In addition, Zhuang et al [19] did not consider the solubility of Cu in ␥Ce and ␦Ce and that of Ce in Fcc Cu. Therefore, the Ce-Cu system was reassessed in this work.…”

“…For this reason, Fitzner and Kleppa re-determined the enthalpies of mixing of liquid at with either small pieces of melted solid phases including Cu 6 Ce and Cu 2 Ce were obtained from the measured heats of reaction at 1473 K and the heat contents of the reaction products at the same temperature [18]. Zhuang et al [19] have evaluated the Ce-Cu system thermodynamically before. Experimental phase diagram data [10,11,13,14], enthalpies of mixing of liquid alloys [16,18] and heat contents [20,21] were used in their optimization.…”

a b s t r a c tThe Ce-Cu binary system has been thermodynamically reassessed by CALPHAD approach based on experimental data and thermodynamic properties of phase diagram. Incorporating the thermodynamic evaluations of Al-Ce and Al-Cu systems from literature, the Al-Ce-Cu ternary system has been assessed using CALPHAD approach. The solution phases including liquid, Fcc and Bcc were treated as substitutional solution phases and the Redlich-Kister polynomial was used to describe their excess Gibbs energies. All binary and ternary intermetallic compounds were treated as stoichiometric phases and their Gibbs energies of formation were optimized. The calculated Al-Ce-Cu phase diagram agreed well with available experimental data.

“…1(b), it is clear that the values of S E are very small and it would not cause a large error if ignoring the values of S E in practical computation. From Cu-Ce binary phase diagram, 18) eight points between 1071 K and 1211 K were chosen to calculate the Gibbs freeenergy of Cu 6 Ce phase precipitation reaction. Figure 2 shows the relationships between ÁG ª and T for precipitation reactions of Cu 6 Ce in Cu-Ce binary alloy.…”

The mixing enthalpy (¦H), the excess entropy (S E AB ), the excess Gibbs free-energy (G E AB ) and the component activities (a) of Cu-Ce binary alloy system were calculated based on Miedema's model and some general thermodynamic relations. Results showed that the values of ¦H, S E AB , and G E AB of Cu-Ce binary alloy in 1555 K were all negative in the whole range concentration. The activities of Cu and Ce had negative deviation from Raoult's Law, which indicated that there was a strong interaction between Cu and Ce. The calculation results of the mixing enthalpies and the activities of Cu and Ce agreed well with the experimental results. Cu 6 Ce phase precipitation behavior in thermodynamics and dynamics were also discussed. Furthermore, combining the experiment, the existence of Cu 6 Ce phase particles was observed using scanning electron microscopy (SEM) and energy dispersion spectrometry (EDS).
