摘　　要： 高熵合金是最近发展起来的新型多主元合金,一般由五种以上主要元素构成,每种元素的摩尔含量在5%~35%之间。因此,高熵合金的组织和性能特点在许多方面有别于传统合金。本文阐述了高熵合金的定义、特性以及相关热力学原理,介绍了最近几年来国内外在高熵合金领域取得的实质性进展。 High-entropy alloys were newly developed alloys that were composed, by definition, of at least five principal elements with concentration in the range of 5%-35% （molar fraction）. Therefore, the alloying behavior of any given principal element was significantly affected by all the other principal elements presented. The definition, distinguished structure and performance characteristics, as well as the potential applications of high-entropy alloys were introduced. In addition, the historical development and the latest research progress in this field are also summarized.
