Abstract
Nanopowders of Cu and ZrO2 were synthesized from 2CuO and Zr by high energy ball milling. The powder sizes of Cu and ZrO2 were 20 nm and 30nm, respectively. A dense nanocrystalline 2Cu-ZrO2 composite was consolidated by a high frequency induction heated sintering method within 1 minute from the mechanically synthesized powders(2Cu-ZrO2) and horizontally milled 2CuO+Zr powders. The average hardness and fracture toughness values of nanostuctured 2Cu-ZrO2 composite were investigated.

Keywords: High frequency induction heated sintering, Composite, Nanomaterial, Mechanical properties, Cu-ZrO2.
