Paper Title:
Synthesis of Ti(C,N)/Al2O3 by Mechanically Induced Self-Propagating Reactive Synthesis
  Abstract

Ti(C,N)/Al2O3 in situ solid solution composites have been synthesized by mechanically induced self-propagating reactive synthesis (MSR) from the mixture of Ti, Al, C and TiO2 in nitrogen milling atmosphere. The phase transformation and powder morphology characteristics were studied by using XRD and SEM. Full dense and pure Ti(C,N)/Al2O3 composites were fabricated at 1450 °C for 1 h under 10 MPa. The phase composition, microstructure and some mechanical properties of the composites were investigated. The results show that the synthesized Ti(C,N)/Al2O3 composites posses a density of 4.66 g/cm3 and a good combination of mechanical properties of hardness of 25.54 GPa and the flexural strength of 404 MPa. The reaction process mechanism was also discussed.
