Abstract: | In the present paper the structure formation process of the powder metallurgical produced copper composite materials was studied. The volume part of the reinforcing SiC particles was varied from 5 to 25 wt.‐%. It was discovered that while milling in a planetary activator first of all a “puff‐ pastry” structure appeared. There are important differences between this structure formation process and other known processes of milling. The homogeneous distribution of SiC particles was obtained after 60‐100 minutes of treatment in “Gefest11‐3” planetary activator. Phase composition of the powder and composite samples at the interface SiC/Cu (particles/matrix) was analysed after consolidation of the powder mixture and after the high temperature annealing. It was still determined that not only pure copper powder can be as a starting material for Cu‐composites production used, but also the wastes of copper mechanical treatment, for instance, copper shaving. |
