Abstract

High-entropy carbides are a new class of inorganic compounds promising for a wide range of applications. A new concept was proposed for the synthesis of powders of high-entropy carbides by self-propagating high-temperature synthesis (SHS) in the gasless thermal explosion mode from previously mechanically synthesized and structured reaction mixtures. For the first time, high-entropy carbides TaTiNbVWC₅ and TaNbVMoWC₅ were produced by this method, and their crystal structure was determined and compared with those of similar compounds synthesized by sintering.

无气热爆炸模式自蔓延高温合成高熵碳化物

摘要

高熵碳化物是一类新型无机化合物，具有广泛的应用前景。提出了一种新概念，通过在无气热爆炸模式下自蔓延高温合成（SHS）从先前机械合成和结构化的反应混合物合成高熵碳化物粉末。首次利用该方法制备了高熵碳化物TaTiNbVWC ₅和TaNbVMoWC _{5 ，测定了它们的晶体结构，并与烧结合成的同类化合物进行了比较。}
