The metallothermic (calcium hydride) synthesis of Ti–Nb alloy powders alloyed with tantalum and zirconium is experimentally studied under various conditions. Chemical, X-ray diffraction, and metallographic analyses of the synthesized products show that initial oxides are completely reduced and a homogeneous β-Ti-based alloy powder forms under the optimum synthesis conditions at a temperature of 1200°C. At a lower synthesis temperature, the end products have a high oxygen content. The experimenta...

The energy parameters of the model of a pseudoregular ionic solution are estimated for binary oxide phase diagrams in seven systems containing titanium oxide. The obtained parameters are compared to the available theoretical and experimental data on the thermodynamic properties of TiO2 in liquid binary systems. The model of a pseudoregular ionic solution is extended to the liquid eight-component FeO-MnO-CaO-MgO-SiO2-CrO1.5-AlO1.5-TiO2 system, as applied to metallurgical slags containing titanium...

The oxygen activity is studied by oxygen sensors during the oxidation period in experimental heat of a superalloy in a 5-t electric arc furnace. The results of chemical analysis of metal and slag samples are used to calculate the activities of the metallic and oxide solution components using the energy parameters of the models of a pseudosubregular solution for the melt and a pseudoregular ionic solution for the slag, which were determined and presented in our earlier works. Equations are derive...
