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.
