The aim of this work was to study the structure and particle size of copper based composite materials reinforced with a high content (15-35 wt-%) of silicon carbide and prepared by mechanical alloying in the high energy planetary mill. Raw materials consisted of grinded copper chips with a size of < 5000 mu m and reinforcing particles with an initial size of 10 mm. Duration of milling was 20-80 min. It was shown that the formation of Cu-(15-25 wt-%) SiC composites occurred successfully. With an increase in the silicon carbide content of above 25 wt-% (48 vol.-%), the efficiency of mechanical alloying was decreased. The average size of composite particles was similar to 20 mu m.
