摘要：
The structure and properties of composite materials based on copper, strengthened with diamond nanoparticles in an amount of 10 – 35 vol.%, are studied. the starting matrix raw material is coarse copper particles with a size of about 1000 μm. Materials in the form of granules are prepared by mechanical alloying after treatment in a planetary ball mill for 1 – 10 h. Granules are hot pressed at 500°C. The effect of prolonged mechanical alloying on copper – diamond composite material microstructure is studied. The effect of diamond content on composite material microhardness and thermal expansion coefficient is determined.
