Abstract
The thermodynamic and kinetic parameters of the metal melt of a Ti–Al–Zr–Sn–Mo–Nb–Si system alloy were determined, which made it possible to refine the model of element evaporation in multicomponent alloys during electron beam melting with an intermediate crucible. It was demonstrated that the developed mathematical model adequately describes the evaporation of elements during electron beam melting of heat-resistant alloys of the Ti–Al–Zr–Sn–Mo–Nb–Si system, as confirmed by fullscale experiments. The regularities of alloy element evaporation during electron beam melting were established, enabling prediction of the final chemical composition of the ingots and determination of optimal melting parameters. 20 Ref., 2 Tabl., 3 Fig.
