钛/钢异种金属熔化焊研究进展
Research progress in fusion welding of titanium/steel dissimilar metals
摘要
Abstract
Titanium/steel(Ti/Fe)dissimilar metal composite components can fully utilize the advantages of titanium alloys,such as high specific strength,excellent corrosion resistance,and high-temperature stability,while also incorporating the benefits of steel,including high stiffness,low cost,and good machinability.However,the substantial differences in physical and chemical properties between Ti and Fe pose major challenges for the welding of titanium/steel dissimilar metal composites.Due to the advantages of good formability,strong adaptability,and high efficiency,fusion welding joints have garnered significant attention in the field of joining titanium/steel dissimilar metals in recent years.This paper systematically reviews the research progress of laser welding,arc welding,electron beam welding,and other processes,analyses the effects of different fusion welding processes,interlayers,and metallurgical products on the microstructure and properties of joints,and reveals the intrinsic relationship between process-microstructure-properties.Based on this analysis,the existing problems and future research directions of titanium/steel welding technique are summarized,such as the process improvement can not avoid the problems of intermetallic compounds,the limitations of single metal interlayer,and the complexity of composite interlayer scheme.The future research directions,such as metal high entropy alloying,machine learning aided design,and multi-process coordination are proposed to provide technical and theoretical support for the breakthrough of titanium/steel high-quality welding technique and speed up the engineering application process of titanium/steel composite components.关键词
