Abstract Scope The purpose of this work is production of structural or functional two-phase materials from metal powder with intermetallic structure. Investigate the structure formation in intermetallic γ-TiAl alloys by using a complex plastic deformation technology under non-stationary temperature conditions with niobium doping. Mathematical model aimed at obtaining γ-TiAl alloys with a given structure and properties is proposed and implemented, based on the use of data on the features of the physical modeling of the SHS-pressing process. For a mathematical description of the process, it is necessary to determine a system of equations that takes into account the distribution of the thermo-kinetic and rheological properties of the synthesis product in a mold and caliber. High-temperature synthesis of intermetallic compound γ-TiAl in a powder mixture of pure elements in the conditions of SHS-pressing allows to obtain an intermetallic alloy with an average grain size of ~ 30 microns.
