Research progress in high-entropy carbide ceramic materials

Abstract

In recent years， high-entropy ceramics have attracted extensive attention from scholars at home and abroad because of their superior properties to traditional ceramic materials and ability to meet the needs of extreme service environments better. Thanks to the “high-entropy effect”， high-entropy carbide ceramics have better mechanical properties， oxidation resistance， and high-temperature stability. In this paper， we briefly introduce the research status of high-entropy ceramics and summarize the preparation methods of high-entropy carbide ceramic powders and blocks. The mechanical properties， thermal conductivity， oxidation resistance high-temperature stability， and ablation resistance of high-entropy carbide ceramics are reviewed and discussed， and the application of machine learning in the development of high-entropy ceramics is briefly discussed. Finally， in view of the existing problems in the research of high-entropy carbide ceramic materials， the development of new systems， preparation methods， high-temperature performance testing， machine learning， and theoretical calculation are summarized and prospected.
