The new mesostructural composite (МC) is investigated. The base of the MC is copper and the reinforcing components are inclusions-aglomerates of nanocomposite Cu-TiB2. MC was obtained by quasidynamic pressing and it is thermally stable material, which combines high conductivity with the strength properties and wear resistance, significantly superior to the similar characteristics of pure copper. Deformation of the MC in single and low-cycle uniaxial compression, the microhardness for different types of loading are investigated. Changing of the wear resistance of MK as a function of TiB2 is percentage is analyzed. Comparison of macro-mechanical properties of the material features of the microstructure evolution take place. Comparison of the results with the analysis of existing theories of hardening of heterogeneous materials made it possible to determine the mechanism of hardening of the new MC. This makes it possible to optimize the choice of the MC depending on the functional purpose of the material.
