摘要
高熵合金是近年来新兴的一类合金材料,将其用于工程装备领域的同种或异种结构材料焊接,能充分发挥出高熵合金的特性和性能优势,具有广阔的应用前景。本文首先就高熵合金的特点及焊接性进行了分析,然后综述了高熵合金同种或异种材料连接常见的焊接技术研究现状,包括电弧焊、激光焊、电子束焊、扩散焊、搅拌摩擦焊和其他。最后总结了不同焊接技术在相同或不同材料的高熵合金焊接过程中存在的问题,并针对存在的问题提出了以后高熵合金焊接的重点研究方向,以期对高熵合金在焊接领域的应用发展提供参考。
High-entropy alloys are a new kind of alloy material in recent years.When they are used to weld the same or different structural materials in the field of engineering equipment,they can give full play to the characteristics and performance advantages of high-entropy alloys and have broad application prospects.This paper first analyzes the characteristics and weldability of high-entropy alloys,and then summarizes the research status of common welding technologies of high-entropy alloys connecting the same or different materials,including arc welding,laser welding,electron beam welding,diffusion welding,friction stir welding and others.Finally,the problems of different welding technologies in the welding process of the same or different materials of high-entropy alloys are summarized,and the key research directions of high-entropy alloys welding in the future are put forward according to the existing problems,in order to provide reference for the application and development of high-entropy alloys in the welding field.
