Research Status and Prospects of Corrosion Resistance of High Entropy Alloys
Published 2024-12-01“…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.…”
