Integrated research works were carried out on producing ingots of heat-resistant titanium alloy of Ti–Si–Al–Zr–Sn system and subjecting to hot plastic deformation for manufacture of rods-semi-products. The scheme of charge calculation was improved and the technological parameters of electron beam melting of ingots in a modernized electron beam installation UE-208M were determined. Chemical composition and structure of produced ingots of titanium alloys of the Ti–Si–Al–Zr–Sn system were investigated and it was shown that the material is characterized by a rather high chemical homogeneity. Hot deformational treatment of ingots of the electron beam melting was performed and the quality rods-semi-products of heat-resistant alloy of Ti–Si–Al–Zr–Sn system were produced. Ref. 11, Tabl. 1, Fig. 4.
Key words: heat-resistant titanium alloy; ingot; electron beam melting; technological modes; chemical composition; structure; deformational treatment
