To improve the operational characteristics of blades of gas turbine engines of the I and II stages, the modernization of design of the casting installation for the high-gradient crystallization was carried out, as well as an additional introducing of rhenium and tantalum into the base of heat-resistant corrosion-resistant alloy of KhN57KVYuTMBRL-VI type was proposed. The article presents a complex of works on the development of a new alloy composition and features of the technological process for producing the GTE parts with a regular oriented structure. 17 Ref., 4 Tables, 5 Figures.

Key words: casting installation for high-gradient crystallization; superalloys; Rhenium; Tantalum; directional solidification; GTE blades
