摘要
对异种金属焊接接头的焊缝区、熔合区与热影响区的显微组织及元素分布的研究现状进行了综述,指出焊接接头的熔合区易发生失效,对改善异种金属焊接构件的服役组织提供了思路和依据.
Current research status on microstructure and elements distribution in welding seam,fusion zone and heat affected zone were reviewed in this paper.The microstructure leading to failure at the corresponding fusion zone was pointed out.It will provide researchers with thinking and ground to improve the control factors of excellent microstructure for dissimilar metal welding joint with excellent service life.
