摘要
相比传统合金,高熵合金在力学性能方面表现出色,是近年来合金研究的一个热点方向.难熔高熵合金主要由难熔金属元素组成,其强度高、耐高温,因而在极端环境下应用的潜力巨大.但目前难熔高熵合金还存在着强塑性不匹配、加工性能差等问题,调控难熔高熵合金的微观结构进而改善其强塑性是研究的重点.综述对比了近年来难熔高熵合金的不同制备方法对其性能的影响;探讨了调控金属元素和非金属元素对其微观组织和力学性能的影响,并调研了热机械加工工艺对难熔高熵合金的力学性能影响.
Abstract
Compared with traditional alloys,high entropy alloys possess excellent mechanical properties,which have become a hot spot in recent years.Refractory high entropy alloy is mainly composed of refractory metal ele-ments,which has high strength and high temperature resistance,so it has great potential for application in ex-treme environment.However,there are still some problems such as strength-plastic mismatch and poor process-ability in refractory high entropy alloys.It is the focus of research to regulate the microstructure of refractory high entropy alloys then improve strength and plasticity.In this paper,the preparation methods of refractory high entropy alloys were compared,the effects of regulating metal and nonmetal elements on microstructure and me-chanical properties of refractory high entropy alloys were discussed.At the same time,the functions of thermal machining on mechanical properties of refractory high entropy alloys were investigated.
