Project is focused on developmet of an optimal metallurgical process of high reactive and hardly meltable Ti (TiAl, TiB2,etc.) based intermetallic alloys and research of new original systems suitable for extreme working conditions like high temperature, aggressive atmosphere, high mechanical and temperature loading. New intermetallic alloys will be designed in order to reach fine-grained polyphase structure without requirement of their further thermal treatment after casting, this ensure them required toughness at the room temperature, low level of residual stresses, optimal mechanical properties at elevated temperatures, as well as high resistivity against oxidation and aggressive atmosphere. Required chemical composition and lower price of new generation of TiAl based polyphase intermetallic alloys will be achieved using preforms prepared from initial row materials by an original method of isostatic reaction compaction followed by remelting in plasma or arc furnaces. This approach will provide significant improvement of their chemical homogeneity, high flexibility of alloying with required additions, minimization of content of impurities what will provide required properties for their applications in extreme conditions. Moreover, optimised technological process with lower number of remelting cycles will contribute to price reduction of final products that can be used especially in automobile and aircraft engines, power industry, jet engines and biomedical applications as well.
