Abstract：Al2O3-TiC particles reinforced ferro-matrix composite were successfully prepared by in -situ synthesis from ilmenite. The effects of in -situ synthesis and adding synthesis on microstructures and properties were analyzed by using XRD, SEM and mechanical testing methods. The results show that the reinforcing phases of the synthesis ferro-matrix composite comprise of Al2O3, MgAl2O4, TiC and Fe. Some of the TiC phases are oxidized during the synthesis process. The iron matrix of in -situ synthetic composite is distributed as thick block strip and the iron matrix of adding synthetic composite is in a uniform distribution. The properties of synthetic material are excellent. The optimal flexural strength and Vickers hardness are 937MPa and 532, respectively.
