| Abstract: | SiCp/Fe composites are fabricated by an electric current heating dynamic process hot-pressing and rapid densification, which overcomes the limitations of powder metallurgy and casting. The densification behavior and mechanical properties of the iron matrix composites with 10vol% SiC in different voltages and sintering time are investigated. The SiCp/Fe composite fabricated by this process achieves a relative density of 99.6 %, a Brinell hardness of 477HB, a tensile strength of 912MPa and the refined microstructure. |
