摘要：
Cu and Al2O3 nanopowders were synthesized from 3CuO and 2Al by high energy ball milling. The powder sizes of Cu and Al2O3 were 14 nm and 133 nm, respectively. A dense nanocrystalline 3Cu-Al2O3 composite was consolidated by a high frequency induction heated sintering method within 2 minutes from the mechanically synthesized powders. The average hardness and fracture toughness values of the nanostuctured 3Cu-Al2O3 composite were 520 kg/mm2 and 5 Mpa·m1/2, respectively.
