摘要:

高熵陶瓷作为新型材料, 较大的构型熵赋予其独特的性能, 其中高熵过渡金属碳化物有望成为高超声速飞行器热防护系统的备选材料。相比于单组元碳化物陶瓷, 高熵化的单相陶瓷在综合性能上有较大地提高。目前, 高熵过渡金属碳化物陶瓷的研究还处于初始阶段, 关于高熵过渡金属碳化物的成分设计和理论分析还缺少足够的研究支撑。另外, 如何制备高纯度高熵过渡金属碳化物还需要进一步探索。在高熵过渡金属碳化物陶瓷的性能方面, 还缺少深入的研究。本文针对高熵陶瓷的理论设计和制备方法展开综述, 详细介绍了高熵过渡金属碳化物的力学、热导及抗氧化性能的研究进展, 并指出了高熵过渡金属碳化物陶瓷在超高温陶瓷领域存在的科学问题, 展望了高熵过渡金属碳化物陶瓷未来的发展方向。

Abstract:

As a new emergence material, high-entropy ceramics possess unique properties due to its high configurational entropy. Among these ceramics, high-entropy transition metal carbide ceramics (HETMCC) are expected to be the potential candidates for the thermal protection system of hypersonic aircraft. Compared with single-component ceramics, the comprehensive performance of single-phase HETMCC is greatly improved. At present, the research on HETMCC is still in the initial stage, and the composition design and theoretical analysis of HETMCC are lack of sufficient research support. In addition, it is necessary to further explore the preparation of high purity HETMCC. In terms of the properties of HETMCC, further in-depth research has been conducted. In this paper, the theoretical design and preparation methods of high-entropy ceramics are reviewed. Research progress of the mechanical properties, thermal conductivity, and oxidation resistance properties of HETMCC are introduced in detail. The concerned scientific issues of HETMCC are pointed out and their future development direction are also prospected.

Key words: high-entropy transition metal carbide, configurational entropy, mechanical property, thermal conductivity, oxidation-resistance, review
