Thermodynamic properties of uranium-aluminum alloys

Thermodynamic optimization of La–Zn and La–Mg–Zn systems

“…The calculated activity coefficients of La in the Zn-1.4 wt.% La alloy, as shown in Fig. 4, are in good agreement with the experimental data [18,19]. The calculated Gibbs energy of formation of LaZn 11 at 723 K comparing with the experimental data [20,21] is plotted in Fig.…”

“…Mullayanov et al [18] and Lebedev et al [19] determined the activity coefficient as a function of temperature from 715 K to 1017 K by EMF method. The calculated activity coefficients of La in the Zn-1.4 wt.% La alloy, as shown in Fig.…”
