Literature data are given about physical and mechanical properties of the titanium intermetallics, which are most important for practical application. Due to unique properties the titanium intermetallics find the wide spreading in: medicine (manufacture of stents, (endo) prostheses, implants), engine manufacturing, power-generating and turbo- ventilation units, gas turbine systems, rocketry, aircraft industry, armored vehicles, chemical machine building, food industry and motor-car construction. Peculiar features of such intermetallics as aluminides, silicides, borides and nickelides of titanium are considered. Information is given about prospects of their application. Except the melting of parts of intermetallics by using a centrifugal casting, the scientists are mostly prone during recent years to applying the additive technologies. Main methods and power sources for producing 3D products are given. Ref. 29, Figures 4.

Key words: intermetallic compounds; titanium aluminides; titanium silicides; titanium borides; titanium nickelides; properties; additive production
