As a result the region of existence of univariant eutectic transformation with its participation, the presence of transformations in the solid state with the formation of TiAlCr or AlCr2 intermetallics, the influence of alloying on the structure, melting temperature, phase composition and mechanical properties were determined. It has been shown, that transition from single-phase alloys to eutectic is accompanied by enhancement of both strength and plasticity, while retaining a high elastic modulus and high thermal stability of mechanical properties at temperatures 20-800 °C. The eutectic alloys are characterized by high heat resistance up to 1000 °C, that makes their perspective for creation on their basis of coatings on TiAl base alloys.
