Summary

The processes of structure formation of copper alloys, by their reacting in liquid state with cast iron at temperatures below and above the melting temperature of cast iron. It is found that the structure, phase composition and elemental composition of copper alloys depend on the temperature and the kinetic parameters of the process. Mechanism of dispersion strengthening of copper by dispersed particles of chromium carbide, the source of which is chromium cast iron, is proposed.
