“…The phase equilibria calculated using our database and the Zircobase [21] agree well with the measurements of Liu et al [74]. Moreover, our predictions of the SPP after annealing at 1023 K are in good agreement with the measurements of Jianlie et al [75]. Nevertheless, a significant gap remains concerning the decomposition of Ti 2 Ni between the measured temperature and the calculated one with our and Zircobase descriptions [21].…”

“…We have reported in Table 10 and 11 the SPP of this quinary alloy predicted by our new database compared to measurements of Jianlie et al [75] and Liu et al [74] as well as the predictions of the Zircobase [21]. We also reported in Table 11 the decomposition temperatures of the stable SPPs.…”

“…Liu et al [74] reported the existence of the two SPP with hexagonal and cubic crystal structures. At higher temperature, the measurements of Jianlie et al [75] show that three SPP are stable with C14, Ti 2 Ni and FeZr 3 structures, respectively.…”

“…The first one exhibits a composition close to that of Zy-4 with 1 wt.% Sn, the second one has a composition closer to that of M5 ® with 1 wt.% Nb. 4.6.1 Second Phase Particules (SPP) in a Zr-1.0Sn-0.3Nb-0.3Fe-0.1Cr alloy This quinary industrial alloy has been experimentally studied by Liu et al [74] after annealing for two hours at 863 K and Jianlie et al [75] after annealing for two hours at 1023 K then heating up to 1273 K. The authors determined the phase equilibria using XRD and TEM (Transmission Electron Microscopy). Jianlie et al [75] also measured the decomposition temperatures of the SPP between 1023 K and 1273 K by calorimetry.…”

This paper is dedicated to the Calphad modelling of the Cr-Fe-Nb-Sn-Zr quinary system. In previous papers, the thermodynamic modelling of the Cr-Nb-Sn-Zr quaternary system, the Fe-Sn-Zr and Fe-Nb-Zr ternary systems as well as the Fe-Nb binary system were carried out. Since no experimental data were available for the Cr-Fe-Sn and Fe-Nb-Sn ternary systems, new partial isothermal sections have been measured at 1073K and 973K, respectively. In addition to these experimental data, Density Functional Theory (DFT) calculations are performed in order to determine formation enthalpies of the stable and metastable ordered compounds. At last, the Special Quasirandom Structures (SQS) method is used together with DFT calculations in order to calculate the mixing enthalpy of the A2 (bcc) binary solid solution. Finally, these experimental and calculated data are jointly used with those from the literature as input data for the Calphad modelling of the Cr-Fe binary system as well as the Cr-Fe-Nb, Cr-Fe-Sn, Cr-Fe-Zr and Fe-Nb-Sn ternary systems. The ternary 2 systems are then combined into a quinary database for which application examples are provided.

“…It should be noted that the formation of bZr and dissolution of bNb occurred simultaneously during heating, which would be accompanied with the formation and disappearance of other second phase particles. This point should be kept in mind while interpreting phase transformations of Zr-based alloys by using thermal analysis techniques, such as resistivity [26], DSC and DTA [27].…”
