Mathematical modeling methods were used to study the thermal condition of titanium alloy ingots at electron beam melting, taking into account the hydrodynamic flows and processes of chemical element evaporation during electron beam melting of high-strength structural titanium alloys. Proceeding from calculations conducted within the scope of the mathematical models, technological modes were determined and technology was developed for electron beam melting of high-strength titanium alloy ingots, ensuring the high quality of the produced metal. Work to produce the semi-finished products was performed, and the high quality of titanium alloys, obtained by the developed electron beam melting technology, was demonstrated.
