摘要

The effect of TiB2 addition on sinterability and mechanical properties of B4C material was investigated. It was found that addition of TiB2 aids the sintering process and permits pressureless sintering at temperatures between 2050 and 2150 °C. This also alleviates grain growth during sintering. The relative density reaches 98.5% of the theoretical density by increasing the percentage of TiB2 in the composition. The mechanical properties such as hardness, fracture toughness, and bending strength were improved remarkably by addition of TiB2.
