Abstract
B 4 C 含量对(Ti 0.25 Zr 0.25 Hf 0.25 Ta 0.25 )B 2 -B 4 C 陶瓷力学性能及抗氧 化性能的影响 刘国昂，王海龙，方成，黄飞龙，杨 欢 (郑州大学材料科学与工程学院，郑州 450001) 摘 要: 新型高熵硼化物陶瓷具有优异的高温稳定性、低热导率等优点，在高温热防护领域具有广阔的应用前景。本研 究采用硼/碳热还原法结合热压烧结技术在 1900 ℃下制备了(Ti0.25Zr0.25Hf0.25Ta0.25)B2-B4C高熵硼化物陶瓷， 并研究了 B4C 第二相含量对其力学及抗氧化性能的影响规律。结果表明，B4C 均匀分布在高熵基体中，并有效改善了高熵陶瓷的相对 密度和力学性能。当 B4C 体积分数为 20%时，复相陶瓷的抗弯强度、断裂韧性以及维氏硬度值均达到最高值，分别为 (570±27.6)MPa、(5.58±0.36)MPa .m 1/2 和(24.6±1.1)GPa。微结构分析表明，B4C 能够钉扎晶界、细化晶粒，并能够引入 裂纹偏转、分支等增韧机制，最终实现复相陶瓷的强化及韧化。此外，利用静态氧化实验，揭示了 B4C 含量对复相陶 瓷 800~1400 ℃抗氧化性能的影响。当
