Abstract

Copper matrix composites containing different volume fractions of B₄C particles (0–15%) were first fabricated by spark plasma sintering followed by hot rolling in atmospheric environments, then their microstructures, phase compositions, mechanical properties and sintering mechanism were investigated. It was found that B₄C particles distributed relatively homogeneously in the copper matrix. Reaction products of CuC₈ and B were observed and identified in the composite. Under increasing B₄C particle content, the ultimate tensile, yield strength and elongation to fracture of the composites decreased. Failure mode of composites included: (1) the interfacial debonding and (2) the cleavage fracture of copper. Moreover, micro-discharge between the adjacent particles occurred, and its led to local high temperature at the interface.
