Purpose - to study the possibility of creating alloys that have included strengthening phases formed by two mechanisms: primary - emulsification of melt temperature and concentration of two-phase region and secondary - due to the evolution of the supersaturated solid solution during aging. Methods: rezystometrii method for investigating changes in the structure of the alloy at different temperatures in an inert environment, and microanalysis - to study the distribution of elements and compositions of phases metallography method - to study the structure of alloys. Tested fusions of Cu - (Ni - Si) - (Fe - Cr - C), the composition of which ensures the existence of two-phase liquid state. Structural components of alloys of this system are: phase based on copper, inclusions (Fe - Cr - C), formed in the melt, and the inclusion, resulting from reduced solubility of elements in solid solution based on copper cooling. The interaction of these phases contributes significantly increase the upper threshold temperature at which the alloy is able to maintain acceptable performance of mechanical and special properties compared to hardened K1N3 bronze. Confirmed the possibility of obtaining copper hardened cast composites reinforced inclusions formed by the mechanism of aging, on the basis of Cu - (Ni - Si) - (Fe - Cr - C).
