| Abstract | ||
| The oxide dispersion strengthened copper alloys are attractive due to their excellent combination of thermal and electrical conductivities, high-temperature strength and microstructure stability. However, the state-of-art to fabrication of them was the internal oxidation (IO) process. In the paper, alumina dispersion strengthened copper (ADSC) powders of nominal composition of Cu-2.5vol%Al2O3 were produced by reaction milling (RM) process which was an in-situ gas-solid reaction process. The bulk ADSC alloys for electrical and mechanical properties investigation were obtained by sintering and thereafter hot extrusion. After the hot consolidation processes, the fully densified powder compacts can be obtained. | ||
