    Notes: Conclusions The directional solidification of the eutectic in the refractory oxide systems results in the formation of a plate-shaped or fibrous oriented composite structure. The theoretical fundamentals of the method of directionally solidified eutectics, developed on the basis of the metallic systems, can also be applied extensively to refractory oxide DSEs so that their structure and composition can be controlled in the required direction. The orientation relations between the phases of the refractory oxide DSEs and the construction of the interphase boundaries result in the formation of semicoherent interphase boundaries. This is one of the conditions for the higher and thermal stability of the materials. The mechanical properties of the materials based on refractory oxide DSEs are controlled by the structure of the oriented eutectic. Disruption of flat frontal growth in solidification leads to the formation of a cellular structure. The cell boundaries are the weakest area of the material and control its behavior during failure. The materials based on the direction solidified refractory oxide eutectics have unique set of the applied properties and are highly promising for use as structural materials at elevated (up to 1500°C) temperatures. The materials made of the refractory oxide DSEs can be used in practice after developing high-productivity methods of their growth which would make it possible to produce components of the required shape.

    Polythermal sections of the Al2O3-ZrO2-Y2O3 phase diagram (1996)

    Notes: Abstract Polythermal sections of the Al2O3-ZrO2-Y2O3 phase diagram confirm that the system is quasibinary and enable one to give a complete phase diagram for the system. The ternary eutectic Al2O3 + ZrO2 (solid solution) + Y3Al5O12 has the lowest melting point in the system, whose temperature is 1715°C. No single-phase regions for the ternary solid solutions have been identified, which indicates that Al2O3 is not soluble in solid solutions based on F-ZrO2 and C-Y2O3. This gives theoretical evidence for the scope for making new ceramics in this ternary system, which may have a high level of mechanical characteristics.

    Interactions in the Ca2SiO4-CaZrO3 system (1996)

    Notes: Abstract X-ray analysis at 20–1200°C and differential thermal analysis have been used to refine the transformation temperatures and unit-cell parameters for crystalline modifications of dicalcium silicate. Phase equilibria have been identified in the Ca2SiO4-CaZrO3 system at 1100–2500°C. The phase diagram for this system has been derived. The characteristic features are the eutectic form for the liquidus and the formation of narrow solid-solution regions based on various crystalline modifications of Ca2SiO4.

    Notes: Abstract The phase diagram of the Al2O3-ZrO2 system was replotted over a broad range of concentrations (0–100 mole %) and temperatures (1150–2800°C). The polymorphic transformation of zirconium F ⇄ T occurs via the metatectic reaction F ⇄ T + L at 2260°C. Phase triangulation was employed to plot the diagrams of the partially quasibinary sections in the Al2O3-ZrO2-Y2O3 system. Since there is a wide solubility range based on ZrO2 in the binary ZrO2-Y2O3 system, the triangulation conodes are displaced in the F-solid solution corners. The two-phase regions Y3A5-F are quite broad. The reactions in all three are of the eutectic type. The ternary solid solution fields in the Al2O3-ZrO2-Y2O3 system had no observable width.
