This paper presents the results of a thermodynamic analysis of equilibrium phase diagrams for systems relevant to the ternary-melt Ti-10V-2Fe-3Al alloy, along with calculations of thermodynamic parameters and a staged thermodynamic prediction of the technological conditions for vacuum arc remelting (VAR). Three remelting stages are justied thermodynamically: the rst melt removes coarse Fe, V, and Al oxides; the second melt breaks down most FeTi/Fe₂Ti intermetallics and transfers part of the titanates into slag; the third melt brings the system close to equilibrium, minimizing oxide and intermetallic inclusions. Practical recommendations were developed based on the thermodynamic analysis, including the required vacuum level (pO₂ ≤ 10⁻²⁰–10⁻²²), control of O, N, and H impurities, requirements for alloying additions, conditions for ternary remelting, and β-homogenizationТип публикаций
