used to determine the microstructure, microhardness and electrical resistivity of as-prepared nanocrystalline Cu, respectively. The results show that the microhardness of nanocrystalline Cu increases.... The electrical resistivity of as-prepared specimens is (1.2-1.4)×10-7 Ω·m at temperature 233-293 K, which is 5-6 times higher than that of the coarse-grained copper. Key words: vacuum-warm-compaction......
