To improve the mechanical properties of B4C ceramics, TiB2 was generated in-situ in B4C ceramics by a reaction sintering method with TiO2 as a sintering aid to prepare dense B4C ceramics, and the enhancement mechanism of its mechanical properties was analyzed. The results show that the density and flexural strength of B4C firstly increase and then decrease and the fracture toughness increases with the increase of TiO2 addition. The density of B4C ceramics reaches 99.6% when the TiO2 addition is 5% (in mass fraction) and the sintering temperature is 1 700 ℃. The optimum overall performance of B4C ceramics (i.e., the Vickers hardness of 36.0 GPa, the fracture toughness of 4.38 MPa·m1/2, the bending strength of 405 MPa) can be obtained when the amount of TiO2 added is 15%. The in-situ TiB2 inhibits the growth of B4C grains, eliminates the stress at the crack tip, deflects and bifurcates the crack, and plays a role in grain refinement strengthening and toughening of B4C ceramics.

以TiO2为烧结助剂,采用反应烧结法在B4C陶瓷中原位生成TiB2,制备出致密的B4C陶瓷,并对其强化机制进行了分析。结果表明:随着TiO2添加量的增加,B4C陶瓷的致密度和抗弯强度先增大后减小,断裂韧性不断增大。当TiO2添加量为5%(质量分数)、烧结温度为1 700 ℃时,B4C陶瓷致密度达到99.6%;当TiO2加入量为15%时,B4C陶瓷的Vickers硬度为36.0 GPa,断裂韧性为4.38 MPa·m1/2,抗弯强度为405 MPa,综合性能最优。原位生成的TiB2抑制了B4C陶瓷晶粒长大,消除了裂纹尖端应力,使裂纹产生偏转和分叉,对B4C陶瓷起到细晶强化和增韧作用。

以TiO2为烧结助剂,采用反应烧结法在B4C陶瓷中原位生成TiB2,制备出致密的B4C陶瓷,并对其强化机制进行了分析。结果表明:随着TiO2添加量的增加,B4C陶瓷的致密度和抗弯强度先增大后减小,断裂韧性不断增大。当TiO2添加量为5%(质量分数)、烧结温度为1 700 ℃时,B4C陶瓷致密度达到99.6%;当TiO2加入量为15%时,B4C陶瓷的Vickers硬度为36.0 GPa,断裂韧性为4.38 MPa·m1/2,抗弯强度为405 MPa,综合性能最优。原位生成的TiB2抑制了B4C陶瓷晶粒长大,消除了裂纹尖端应力,使裂纹产生偏转和分叉,对B4C陶瓷起到细晶强化和增韧作用。

To improve the mechanical properties of B4C ceramics, TiB2 was generated in-situ in B4C ceramics by a reaction sintering method with TiO2 as a sintering aid to prepare dense B4C ceramics, and the enhancement mechanism of its mechanical properties was analyzed. The results show that the density and flexural strength of B4C firstly increase and then decrease and the fracture toughness increases with the increase of TiO2 addition. The density of B4C ceramics reaches 99.6% when the TiO2 addition is 5% (in mass fraction) and the sintering temperature is 1 700 ℃. The optimum overall performance of B4C ceramics (i.e., the Vickers hardness of 36.0 GPa, the fracture toughness of 4.38 MPa·m1/2, the bending strength of 405 MPa) can be obtained when the amount of TiO2 added is 15%. The in-situ TiB2 inhibits the growth of B4C grains, eliminates the stress at the crack tip, deflects and bifurcates the crack, and plays a role in grain refinement strengthening and toughening of B4C ceramics.
