摘要

高熵合金(High-Entropy Alloys， HEA)是一种在高端装备制造业中具有广阔应用前景的新型金属材料。由于高熵合金特有的相结构及“四大效应”赋予其优异的强度、硬度、韧性、抗磨损等力学性能，已使高熵合金成为材料领域的研究热点。腐蚀是金属材料常见且无法避免的失效形式，高熵合金因具有优秀的耐腐蚀性能而被广泛应用于工业领域。因此，需重点研究高熵合金的耐腐蚀性能及耐腐蚀机理与规律，以便更好地研制出高性能高熵合金。首先简单叙述了高熵合金的定义以及高熵合金的分类，其次归纳总结了高熵合金的制备方法，并详细综述高熵合金耐腐蚀性能的研究现状。不同制备工艺以及工艺参数对高熵合金的组织结构有直接影响，且高熵合金组元具有广阔的设计空间，因此通过调控制备工艺参数以及组元成分能进一步优化高熵合金的耐腐蚀性能。最后展望了未来高熵合金的研究主题和研究思路。

Abstract

High Entropy Alloys (HEA) are a new type of metal material with broad application prospects in the high-end equipment manufacturing industry.Due to the unique phase structure and “four major effects” of high entropy alloys， which endow them with excellent mechanical properties such as strength，hardness，toughness and wear resistance，high entropy alloys have become a research hotspot in the field of materials.Corrosion is a common and unavoidable form of failure in metallic materials，and high entropy alloys are widely used in industrial fields due to their excellent corrosion resistance.Thus， it is necessary to focus on studying the corrosion resistance performance， corrosion resistance mechanism and laws of high entropy alloys for better developing high-performance high entropy alloys.This article firstly briefly described the definition and classification of high entropy alloys， then summarized the preparation methods of high entropy alloys， and provided a detailed overview of the research status of high entropy alloy corrosion resistance.Different preparation processes and process parameters had a direct impact on the microstructure of high entropy alloys， and high entropy alloy components had broad design space.Therefore， by adjusting the preparation process parameters and component composition， the corrosion resistance of high entropy alloys could be further optimized.At last，the research topics and ideas for future high entropy alloys were discussed.
