摘要
高熵合金是近年来快速发展的一种新型合金,其成分设计突破了传统合金的设计理念,是合金理论发展的一个新方向.高熵合金所具有的高熵效应、晶格畸变效应、缓慢扩散效应和鸡尾酒效应在焊接领域表现出独特的应用价值,前景十分广阔.文中总结了国内外利用高熵合金四大效应开发焊接材料与工艺的研究现状和存在的问题,并对未来发展方向进行了展望.
High entropy alloys(HEAs) are new generation of alloys which have been developed rapidly in recent years.The composition design of HEAs is a breakthrough of the traditional alloy design idea,and it is a new developing direction of alloy theories.With the high entropy effect,severe lattice distortion effect,sluggish diffusion effect and cocktail effect,the HEAs have promising applications in welding fields.This paper summarized the research status and existing problems in developing the welding filler materials and welding processes utilizing the four effects of HEAs,and the trend of development is prospected as well.
