Mechanical Properties of SiCp/Cu Composites Prepared by Electric Conduction Sintering

Abstract:

Article Preview

SiCp/Cu composites were fabricated at 700 oC and under 40MPa for 10min in vacuum by electric conduction sintering. The mechanical properties and microstructure of the composites were studied. The porosity of the composites increases when the volume fraction of SiCp exceeds 35%. The flexural strength of the composites decreases with increasing fraction of SiCp. The composites with 10 vol.% SiCp exhibited ductile fracture behavior, while composites with the volume fraction of SiCp in the range of 20–65% exhibited brittle fracture behavior. The composites with 35 vol.% SiCp showed the highest hardness.
