Abstract

An optimum route to fabricate the Al2O3/Cu composite with sound microstructure and desired mechanical properties was investigated. The composite having a nano-sized Cu-dispersoid was successfully fabricated by controlled hot-pressing process using Al2O3 and CuO powder mixture as starting materials. The composite exhibited the maximum fracture strength as 819 MPa and enhanced toughness compared with monolithic Al2O3. The influence of processing condition and added Cu-phase upon the mechanical properties was discussed based on the observed microstructural characteristics.
