Abstract
AbstractSpark plasma sintering (SPS) is an advanced sintering technique because of its fast sintering speed and short dwelling time. In this study, TiB2, Y2O3, Al2O3, and different contents of B4C were used as the raw materials to synthesize TiB2‐B4C composites ceramics at 1850°C under a uniaxial loading of 48 MPa for 10 min via SPS in vacuum. The influence of different B4C content on the microstructure and mechanical properties of TiB2‐B4C composites ceramics are explored. The experimental results show that TiB2‐B4C composite ceramic achieves relatively good comprehensive properties and exceptionally excellent flexural strength when the addition amount of B4C reaches 10 wt.%. Its relative density, Vickers hardness, fracture toughness, and flexural strength reach to 99.20%, 24.65 ± .66 GPa, 3.16 MPa·m1/2, 730.65 ± 74.11 MPa, respectively.
