摘要

Based on thermodynamic analysis, fully densified (TiB ₂ + SiC)/Ti ₃SiC ₂ composite ceramics were in situ prepared by hot-pressing at 1350-1500 °C using TiH ₂, TiC, Si, B ₄C and Al powders as raw materials, in which the main phases are Ti ₃SiC _2, TiB ₂ and SiC. As reinforcing agents, columnar TiB ₂ grains and granular SiC grains, incorporated by in situ reaction exhibit significant synergistic strengthening and toughening effect to the Ti ₃SiC ₂ matrix and the composites show excellent mechanical properties. The materials sintered at 1450 °C possess the optimized microstructure and consequently the optimal mechanical properties, i.e., bending strength of 861 MPa, fracture toughness of 9.56 MPa•m ^1/2 and Vickers hardness of 9.79 GPa.
