Abstract
The FeSiB-rich particle-reinforced Cu metal matrix composites (MMCs) were fabricated by sintering core–shell-type composite powders using spark plasma sintering (SPS) technique. Results revealed that the strength (σyc = 548 MPa and σfc = 957 MPa) of composites is significantly enhanced without sacrificing ductility (ε = 29%). The increase in strength is mainly attributed to the homogenously distributed FeSiB-rich reinforcements and high interfacial strength between the Cu-rich matrix and reinforcements.
