摘　　要：本文简述了难熔高熵合金的含义与特点,归纳了各类难熔高熵合金(块体、薄膜、涂层)的制备方法,重点阐述了难熔高熵合金的综合性能。建议通过构建专门的难熔高熵合金数据库优化成分设计,并着重于不同制备方法的工艺性研究。针对目前难熔高熵合金存在室温脆性大、密度大、成本高等不足,提出可根据所需难熔高熵合金的性能而选择不同的制备方法,以便未来工业化应用。The meaning and characteristics of refractory high entropy alloys were briefly described,and the preparation methods of various refractory high entropy alloys(bulk,film and coating)were summarized.The comprehensive properties of refractory high entropy alloys were emphatically expounded.It was suggested that the composition design should be optimized by constructing a special database of refractory high entropy alloys,and the manufacturability of different preparation methods should be focused on.In view of the shortcomings of high room temperature brittleness,high density and high cost of refractory high entropy alloys at present,different preparation methods could be selected according to the properties of refractory high entropy alloys for future industrial application.
