The ferro-matrix composite reinforced by Al2O3-TiC/TiCN particles which was produced by in-situ synthesis from ilmenite were successfully prepared by hot-pressing process.In this paper,the phase,micro-structure and properties are investigated by using XRD,SEM and mechanical testing means.The XRD results show that the TiC/TiCN particles will be oxidized and the intermediate oxide of titanium appears during the sin-tering process.The properties of synthetic material are excellent,the hightest mechanical property of the mate-rial for the flexural strength was 1 334 MPa and the vickers hardness was 802.
