Microstructure and mechanical properties of B4C/TiB2 ceramics prepared using different Ti sources
Source abstract
Abstract
In this study, B 4 C/TiB 2 ceramics were prepared by using Ti powders of different sizes and TiB 2 powders as additives. The results show that B 4 C-15 wt% Ti (10 μm, S1) achieved the best overall performance, with the relative density, Vickers hardness, flexural strength, and fracture toughness reaching 99.3%, 32.6 GPa, 433 MPa, and 5.25 MPa m 1/2 , respectively. In this sample, micron-sized TiB 2 aggregates are formed, around which nano-sized TiB 2 grains are dispersed. The micro-sized TiB 2 grains exert a toughening effect by inducing crack deflection, while the nanosized TiB 2 grains undergo fine-grain strengthening. This comprehensive treatment has enabled the B 4 C-15 wt% Ti (10 μm, S1) ceramic to achieve outstanding performance.
