Research on the Hot Pressing Parameters of Ti (C,N)/Al₂O₃ Nanocomposite Ceramic Die Material and the Material Fabrication

Abstract:

In the present study, Ti (C,N)/Al₂O₃ nanocomposite ceramic die material was fabricated through adding nanosize Ti (C,N) powders into micrometer Al₂O₃ matrix by vacuum hot-pressing technology. Effects of the hot press sintering process on mechanical property and microstructure of the nanocomposite ceramic die material were investigated. The optimum hot-pressing technology with the sintering temperature of 1650°C, time duration of 15min and pressure of 30MPa was achieved. The microstructural morphology of the material was also analyzed. It reveals that the intergranular/intragranular microstructure and the resulted intergranular/transgranular fracture mode are the main causes for strengthening and toughening in the nanocomposite ceramic die material.
