Abstract

A mechanochemical method of a single-stage synthesis of a metal matrix composite consisted of copper aluminides, Cu9Al4, reinforced by fine particles of aluminium oxide was investigated. It was demonstrated that CuO and Al can react forming directly g-Cu9Al4 intermetallic compound when the initial content of aluminium is higher than stoichiometric one. It is shown that Al2O3 particles in the synthesized cermet have a size ranging from 500 to 100 nm.
