P. 2933–2957. Formation of “titanium – titanium aluminide” composite materials by the method of spark plasma sintering D.V. Lazurenko, O.E. Matts, K.A. Kuzmin Particularities of the multilayered “metal - intermetallic” materials structure formation were considered. Spark plasma sintering of metal blanks in cylindrical molds at the temperature of 830 о С and 3 kN pressure during 5 minutes was founded as the most efficient technology of formation of materials with intermetallic layers. The regime described above allows fabricating material with high-quality intermetallic layers and up to 3800 MPa microhardness level. Key words: spark plasma sintering, multilayered composites, titanium aluminides.
