Research methods are mathematical modeling, including machine learning, physical modeling, physical experiment, X-ray structural and X-ray phase analysis, registration of transient electrical processes, optical microscopy, experimental methods for determining the physical and mechanical properties of materials. Scientific and technological foundations for the directed high-energy synthesis of multifunctional powder composites with high electrical conductivity and wear resistance based on copper and aluminum powders with high-modulus fillers of the TiC–Ti system by using high-voltage electric discharge and spark plasma sintering have been developed. The technological scheme for creating metal-matrix composites (MMC) has been adapted, which allows to obtain MMC with significantly lower energy costs, which have a specific electrical resistivity of 0.5-1.0 Ohm·mm²/m and a hardness of up to 67 HRB (Cu – Ti – C system) and up to 43 HRB (Al – Ti – C system). The use of the adapted technological scheme allows to increase the heat resistance of MMCs by 6 times, and the wear resistance by 1.7 times. The obtained MMCs can be used in electrical equipment, rocket and space technology, aviation, defense industry, mechanical engineering and shipbuilding.
