    Russian Journal of Inorganic Chemistry, 2020
    Co-Authors: I. Ya. Zaitseva, I. S. Kovaleva, V. A. Fedorov
    Abstract:

    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.

    Russian Journal of Inorganic Chemistry, 2020
    Co-Authors: I. Ya. Zaitseva, I. S. Kovaleva, V. A. Fedorov
    Abstract:

    The interaction of components in the Cs2HgBr4-Cs2ZnBr4-CsBr Ternary System was studied by differential thermal and X-ray powder diffraction analyses. The liquidus surface consists of the crystallization fields of three phases: CsBr, a solid solution of Cs2HgBr4 with Cs2ZnBr4 (α), and solid solution β based on Cs3ZnBr5. The Ternary eutectic near Cs2HgBr4 has the coordinates ∼83 mol % Cs2HgBr4, 2 mol % Cs2ZnBr4, and 15 mol % CsBr and the melting point ∼415°C. The triangulating section Cs2HgBr4-Cs3ZnBr5 is characterized by the eutectic interaction with the eutectic that is degenerate near Cs2HgBr4, contains ∼3 mol % Cs3ZnBr5, and melts at 420°C. This section divides the Cs2HgBr4-Cs2ZnBr4-CsBr Ternary System into two Ternary Systems Cs2HgBr4-CsBr-Cs3ZnBr5 and Cs2HgBr4-Cs3ZnBr5-Cs2ZnBr4.

    Co-Authors: I. Ya. Zaitseva, I. S. Kovaleva, V. A. Fedorov
    Abstract:

    The interaction in the HgBr2-CdBr2-PbBr2 Ternary System was studied by differential thermal analysis; the isoconcentration section of the System at 50 mol % CdBr2 was investigated. Based on the results of the study, a projection of the liquidus surface of the HgBr2-CdBr2-PbBr2 Ternary System to the composition triangle was constructed; the boundaries of the primary crystallization fields were determined for three phases: HgBr2 (degenerate field), solid solution α based on CdBr2, and solid solution β based on PbBr2; and isotherms were drawn. A Ternary eutectic has the composition 93 mol % HgBr2-1 mol % CdBr2-6 mol % PbBr2 and melts at 235°C.

  • experimental study on phase relations in the ce fe sb Ternary System
    Journal of Alloys and Compounds, 2018
    Co-Authors: Chengliang Xu, Changrong Li, Zhenmin Du, Raowen Zheng, Junqin Li
    Abstract:

    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.

    Co-Authors: Jianlie Liang, Junqin Li, X W Feng, Y X Jian
    Abstract:

    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.

    Co-Authors: Shusen Wang, Zhu Li, Shihua Wang, Xionggang Lu, Chonghe Li
    Abstract:

    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.

    Abstract:

    The Ti–Cr–Mn Ternary System is one of the most important Systems in the development of low cost titanium alloys. However, there are few reports of assessment for this System. In this paper, the previous works for the Ti–Cr–Mn System and the related binary sub-Systems are reviewed. The thermodynamic parameters of TiMn3 and TiMn4 in the Ti–Mn System are reassessed in order to better describe the phase equilibrium involving TiMn3 or/and TiMn4 in the Ternary System. Based on the Ti–Cr and the Cr–Mn Systems modeled in the literature and the Ti–Mn System reassessed in this work, the Ti–Cr–Mn Ternary System is assessed by means of the Calphad method using the Ternary experimental data in the literature. The 1173 K and 1273 K isothermal sections are calculated. It is shown that the present calculated results are in good agreement with most of the experimental results.
