Abstract

Mixed copper and carbon powders were mechanically alloyed (MA) in a planetary ball mill. The supersaturated solid solubility of carbon in MA copper was 25at%C which was determined from lattice parameter change. The supersaturated copper powder consolidated by static compression of 1.4 GPa, has the relative density of 95%, and Vickers hardness of 121. Otherwise, that consolidated dynamically by a bullet of 90.1 g at the speed of 38.1 m/s after 0.4 GPa static compression, has the relative density of 96.3%, and Vickers hardness of 200. Keeping the MA effect more than half, MA powders could be consolidated by impact pressure.
