| Abstract: | In order to exploit a kind of ceramic tool material, Al2O3/TiN composite materials were prepared by hot press sintering. The specimens prepared at sintering temperatures of 1700℃, TiN content of 30%, 40%, 50%, 60%, sintering press of 32MPa, holding time of 5min, 10min, 15min. Effects of holding time on mechanical properties and micrestructure of these materi- als were investigated by analyzing the bending strength, hardness, fracture toughness. It is indicated that the holding time has im- portant effect on the microstructure and mechanical properties. |
