摘要: 高强钢焊接过程中焊缝金属与母材的强韧匹配问题一直难以解决,因此急需细化合金元素调控体系,完善高强钢焊缝金属的强化增韧机理。贝氏体是高强钢焊缝金属中的重要组织,对其强韧性有重要影响,因此介绍了典型贝氏体的形成机理及分析方法,重点综述了合金元素对高强钢焊缝金属微观组织和力学性能的影响,得出高强钢焊接中各合金元素推荐值,进而丰富高强钢焊缝金属合金元素调控体系。

关键词: 高强钢, 焊缝金属, 贝氏体, 微观组织, 力学性能

Abstract: In welding processes of high-strength steels, it was difficult to match the strength and toughness between weld metal and base metal. Thus it was urgent to refine regulation and control systems for alloying elements and improve strengthening and toughening mechanism of high-strength steel weld metals. Bainite is the important microstructure and had a significant influence on the toughness of high-strength steel weld metals, so formation mechanism of typical bainite and bainite analysis methods were summarized. The influences of alloying elements on the microstructure and mechanical property of high-strength steel weld metals were reviewed. Values of each alloy element were recommended, which aimed to give reference for regulation and control systems for alloying elements of high-strength steel weld metals. 

Key words: high-strength steel, weld metal, bainite, microstructure, mechanical property
