“…In terms of its physicomechanical properties, the new material is expected to be better than internally oxidized copper alloys characterized by high heat resistance and by thermal and electrical conductivity equal to 95-97% of the corresponding values for pure copper. It is these properties of internally oxidized alloys that allow their applications as electrical contacts, electrodes for electric welding of light (aluminum) alloys, and inserts in windtunnel nozzles [2]. The properties of internally oxidized alloys, however, are restricted by the processes of formation of their structure [3].…”

A thermally stable high-strength mesocomposite containing nano-sized particles of titanium diboride (TiB 2 ) is obtained by combining methods of self-propagating high-temperature synthesis and quasi-dynamic high-velocity pressing. The use of selfpropagating high-temperature synthesis ensured obtaining a hardening component of the mesocomposite -nanocomposite with a TiB 2 particle size of ≈100 nm. The quasidynamic method of obtaining a material characterized by high deformations determines self-organization of the mesocomposite microstructure with an unchanged size of the hardening TiB 2 particles in the inclusion structure. Mechanical properties of the mesocomposite are substantially better than the properties of the composite matrix.Creation of materials with high physical and mechanical properties is one of the basic problems of physical material science. The use of high-energy methods for this purpose is determined by their advantages, namely, generation of high stresses and short-duration impact of the latter. A high-energy action on a substance initiates processes that can be hardly obtained by other methods. A high-energy mechanical action ensures both high stresses and high loading rates, but also an ambiguous response of the material. It was shown [1] that the mechanism of deformation can change under conditions of high loading rates. In this case, the material can acquire properties typical for the nanocrystalline state with the grain size greater than under static deformation conditions by two orders of magnitude.In the present work, the advantages of high-energy actions were used to obtain a new mesocomposite material by the method of quasi-dynamic compaction of a mixture of powders, with the base substance being internally oxidized copper (IOC, Cu-3.5 vol.% Al 2 O 3 )
