Microstructures and mechanical properties of B4C–TiB2 ceramics fabricated by reactive sintering using B4C–Ti mixture

Ceramics International 2025年

作者： Cui, Yi Bao, Sizhuo Sun, Yan Zhang, Ao He, Qianglong Wang, Weimin State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan430070 China School of Materials Science and Engineering Wuhan University of Technology Wuhan430070 China

In this study, B4C–TiB2 ceramics were prepared via reactive sintering using B4C–Ti as the raw material. By investigating the sintering curve, microstructures, and mechanical properties at different sintering temperatures, the liquid-phase sintering environment provided by Ti melting was found to play a key role in densification. The high-speed densification stage occurs between 1800 and 1900 °C, which improves the comprehensive properties of B4C–TiB2 composite ceramics at 1900 °C. B4C–TiB2 composites achieved the best comprehensive properties at 1950 °C. Relative density, Vickers hardness, bending strength, and fracture toughness were 99.3 %, 32.6 GPa, 433 MPa, and 5.25 MPa m1/2, respectively. Vickers hardness and bending strength were affected by density, while fracture toughness was also affected by the TiB2 phase distribution. Additionally, improvement in fracture toughness was the result of the joint action of crack deflection, crack bridging, crack branching, and microcracking mechanisms. © 2025 Elsevier Ltd and Techna Group S.r.l.
