Calculations for an ingot of 300 mm diameter of Ti-Al system intermetallic were conducted within the framework
of the mathematical model of cylindrical ingots crystallization at electron beam melting. As a result of calculations,
temperature fields in the ingot during electron beam melting were obtained, and technological modes of conducting
the process were determined. The determined technological modes were used to produce a large-sized ingot of 300
mm diameter from Ti29Al alloy in electron beam installation UE-121. The quality of this ingot was studied and it was
shown that application of optimized technological modes allows producing large-sized titanium aluminide ingots of
homogeneous composition and without defects. Ref. 12, Table 1, Fig. 6.
