【 摘 要 】

SiCP/Al-Fe-V-Si composite was prepared by spray-deposition. Two kinds of interfaces between SiC particle and the Al matrix were observed in the composite. One was constituted by the glassy silica which could decrease the formation of Al4C3, improve wettability, avoid particle consumption and increase the interfacial strength. The other was a diffusion interface without any interfacial phase which resulted in a high strength bonding at the SiC interface. Fine twinned Al4C3 phases formed in the matrix near the interface, then strengthened the composite further.
