Abstract
A mathematical model was developed of the processes of alloying element evaporation at cold-hearth electron beam melting of ingots of alloys based on titanium aluminide of Ti–Al–Nb–Cr–Mo alloying system that establishes the dependence of alloying element concentration in the ingot on technological parameters of melting and chemical composition of the initial charge. It is shown that the developed mathematical model adequately describes the real evaporation process at electron beam melting of titanium aluminide alloy. The regularities of alloying element evaporation at electron beam melting of alloys based on titanium aluminide of Ti–Al–Nb–Cr–Mo system were established, which allow predicting the chemical composition of the ingots and optimizing the technological parameters of melting. Ref. 21, Tabl. 2, Fig. 5. Key words: electron beam melting; ingot; evaporation; mathematical modeling; titanium aluminide; alloying elements
