Abstract

Cu₈₆Zr₁₁Al₃, a Cu-based composite, was synthesized by copper mold casting. The composite showed a unique microstructure consisting of a ductile Cu crystalline phase and a hard superlattice phase. Uniaxial compression tests revealed a high strength (1.0-1.6 GPa) and fracture strain (9.2-15.0%). We report the mechanism underlying the observed mechanical properties of the composite in relation to its unique microstructure.
