Russian Journal of Inorganic Chemistry, 2020Co-Authors: I. Ya. Zaitseva, I. S. Kovaleva, V. A. FedorovAbstract:Component interactions in the Cs2CdBr4-Cs2ZnBr4-CsBr Ternary System have been studied by differential thermal analysis and X-ray powder diffraction. The liquidus surface is comprised of three crystallization fields: CsBr, a solid solution of Cs2CdBr4 with Cs2ZnBr4 (α), and a Cs3ZnBr5-based solid solution (β). The Ternary eutectic coordinates are as follows: ∼53.5 mol % Cs2CdBr4, 1.5 mol % Cs2ZnBr4, 45 mol % CsBr, and ∼450°C. A Cs2CdBr4-Cs3ZnBr5 triangulating section, which is characterized by peritectic interaction with peritectic (p) coordinates of 20 mol % Cs3ZnBr5 and 480°C, divides the Cs2CdBr4-Cs2ZnBr4-CsBr Ternary System into two Ternary Systems: Cs2CdBr4-CsBr-Cs3ZnBr5 and Cs2CdBr4-Cs3ZnBr5-Cs2ZnBr4.

experimental study on phase relations in the ce fe sb Ternary System
Journal of Alloys and Compounds, 2018Co-Authors: Chengliang Xu, Changrong Li, Zhenmin Du, Raowen Zheng, Junqin LiAbstract:Abstract This paper describes the experimental study on the liquidus projection and the isothermal section at 823 K of the Ce-Fe-Sb Ternary System. The microstructures and solidification paths of the as-cast alloys were analyzed. The constituent phases and their equilibrium compositions of the as-cast and the heat-treated alloys were determined. The microstructure observation, the phase identification and the composition measurement were performed using scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron probe microanalysis (EPMA), respectively. The existence of three Ternary compounds Ce 2 Fe 4 Sb 12 (τ 1 ), CeFeSb 2 (τ 2 ), and Ce 2 Fe 4 Sb 5 (τ 3 ) were confirmed. For the liquidus projection over the entire composition range, there are 17 primary solidification regions, 4 eutectic invariant reactions, and 15 pseudo-eutectic invariant reactions. Some of the primary solidification regions and invariant four-phase reaction types were determined with the help of the thermodynamic assessment of the System. And then the whole liquidus projection of the Ce-Fe-Sb Ternary System was constructed. For the isothermal section at 823 K over the entire composition range, there are 14 single-phase regions, 28 two-phase regions, and 15 three-phase regions. Based on the present experimental measurements as well as the phase diagrams of the three binary subSystems, Ce-Fe, Ce-Sb and Fe-Sb, the liquidus projection and the isothermal section at 823 K of the Ce-Fe-Sb Ternary System were constructed.

Journal of Alloys and Compounds, 2007Co-Authors: Jianlie Liang, Junqin Li, X W Feng, Y X JianAbstract:Abstract Phase equilibria were established in the Eu–Co–Sb Ternary System at room temperature based mainly on X-ray powder diffraction analysis. The binary compounds, CoSb, CoSb 2 , CoSb 3 , EuSb 2 , Eu 2 Sb 3 , Eu 11 Sb 10 and Eu 5 Sb 3 , have been confirmed at room temperature. No binary compound in the Eu–Co binary System or Ternary compound in the Eu–Co–Sb Ternary System was found. The isothermal section of this Ternary System at room temperature consisits of 10 single-phase regions, 17 two-phase regions and 8 three-phase regions. Ten single-phase regions are Eu, Co, Sb, CoSb, CoSb 2 , CoSb 3 , EuSb 2 , Eu 2 Sb 3 , Eu 11 Sb 10 and Eu 5 Sb 3 . The maximum solid solubility of Eu in CoSb 3 at room temperature is less than 0.3 at.%, while the homogeneous ranges of the other single-phase regions are non-observable.

TMS 2017 146th Annual Meeting & Exhibition Supplemental Proceedings, 2020Co-Authors: Shusen Wang, Zhu Li, Shihua Wang, Xionggang Lu, Chonghe LiAbstract:The Al-Fe-Cr Ternary System is one of the most important Systems to developing aluminum alloys. Up to now, although several reviews about this Ternary System have been available, however no thermodynamic assessment was published. In this paper, previous work of the Al-Fe-Cr Ternary System and its related binary Systems are reviewed. Then, Al-Cr binary System was re-assessed in order to better describe the phases Al8(Cr, Fe)5 in Ternary System. Based on the re-assessed Al-Cr binary System and Al-Fe, Fe-Cr binary Systems assessed before, as well as the experimental data reported in the literature, the Al-Fe-Cr Ternary System was assessed by means of CALPHAD method. Isothermal sections of 1433, 1348, 1273, 1173, 1073 and 973 K in Al-rich corner and some invariant reactions are calculated. It is shown that the present calculations are in good agreement with the most of the experimental results.
