Mechanical synthesis and rapid consolidation of a anostructured Cu-ZrO2 composite by high frequency induction heating

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.
