The work is devoted to the study of the influence of mechanical activation, the content of aluminum in the metal binder Fe+Co+Cr+Ni+Al, and compression of samples on the combustion rate, the change in the length of the samples during the synthesis, the morphology and phase composition of the combustion products in the system (Ti+2B)+(Fe+Co+Cr+Ni+Al). Two stages of change in the length of samples from the initial mixtures were recorded: elongation during combustion and shrinkage after combustion. The composite material, which contains high-entropy alloy and TiB, was obtained by SHS method. With an increase in in the combustion products of mixtures (Ti+2B)+(Fe+Co+Cr+Ni+Al), the content of the solid solution phase based on γ-Fe with an FCC-lattice decreased and the content of the solid solution based on α-Fe with a BCC-lattice increased. After mechanical activation, the phase composition of combustion products changes.
