With Pr6O11 and CeO2 as additives, B4C matrix composite materials were prepared at 2 200 ℃, 1 900 ℃, and 1 700 ℃ by adopting techniques of pressureless sintering, hot pressing sintering, and spark plasma sintering, respectively. The relative microstructure and mechanical properties were also studied. It is found that PrB6 and CeB6 formed in situ can fill the pores between B4C grains, and improve the density of the composites. Compared with pressureless sintering and hot pressing sintering, the technique of spark plasma sintering can bring the prepared composites with higher density. The fracture toughness of B4C-CeB6 composites can be improved due to its high relative density, as well as the deflection, branching and bridging of cracks occuring along CeB6, which extends the expansion path of cracks and reduces stress concentration. The B4C-CeB6 composite prepared by spark plasma sintering has good comprehensive mechanical properties, with the relative density, vickers hardness, bending strength and fracture toughness reaching 99.3%, 34.7 GPa, 451 MPa and 4.38 MPa·m1/2, respectively.

分别以Pr6O11和CeO2为添加剂,采用无压烧结、热压烧结和放电等离子烧结法分别在2 200 ℃、1 900 ℃和1 700 ℃制备了B4C基复合材料,并对其微观结构和力学性能进行了研究。结果表明,通过原位反应形成的PrB6和CeB6可以填充B4C晶粒之间的孔隙,提高复合材料的致密性;与无压烧结和热压烧结相比,放电等离子烧结制备的复合材料具有更高的致密性;B4C-CeB6复合材料断裂韧性得以提高的原因是实现了高致密以及裂纹沿着CeB6发生了偏转、分枝和桥联,最终延长了裂纹的扩展路径,降低了应力集中。采用放电等离子烧结制备的B4C-CeB6复合材料综合力学性能较好,相对密度、维氏硬度、抗弯强度和断裂韧性分别达到了99.3%、34.7 GPa、451 MPa和4.38 MPa·m1/2

分别以Pr6O11和CeO2为添加剂,采用无压烧结、热压烧结和放电等离子烧结法分别在2 200 ℃、1 900 ℃和1 700 ℃制备了B4C基复合材料,并对其微观结构和力学性能进行了研究。结果表明,通过原位反应形成的PrB6和CeB6可以填充B4C晶粒之间的孔隙,提高复合材料的致密性;与无压烧结和热压烧结相比,放电等离子烧结制备的复合材料具有更高的致密性;B4C-CeB6复合材料断裂韧性得以提高的原因是实现了高致密以及裂纹沿着CeB6发生了偏转、分枝和桥联,最终延长了裂纹的扩展路径,降低了应力集中。采用放电等离子烧结制备的B4C-CeB6复合材料综合力学性能较好,相对密度、维氏硬度、抗弯强度和断裂韧性分别达到了99.3%、34.7 GPa、451 MPa和4.38 MPa·m1/2

With Pr6O11 and CeO2 as additives, B4C matrix composite materials were prepared at 2 200 ℃, 1 900 ℃, and 1 700 ℃ by adopting techniques of pressureless sintering, hot pressing sintering, and spark plasma sintering, respectively. The relative microstructure and mechanical properties were also studied. It is found that PrB6 and CeB6 formed in situ can fill the pores between B4C grains, and improve the density of the composites. Compared with pressureless sintering and hot pressing sintering, the technique of spark plasma sintering can bring the prepared composites with higher density. The fracture toughness of B4C-CeB6 composites can be improved due to its high relative density, as well as the deflection, branching and bridging of cracks occuring along CeB6, which extends the expansion path of cracks and reduces stress concentration. The B4C-CeB6 composite prepared by spark plasma sintering has good comprehensive mechanical properties, with the relative density, vickers hardness, bending strength and fracture toughness reaching 99.3%, 34.7 GPa, 451 MPa and 4.38 MPa·m1/2, respectively.
