铁素体不锈钢/16Mn钢厚板异种钢电子束焊接接头的组织与冲击韧性
Microstructure and Impact Toughness of Dissimilar Steel Electron Beam Welded Joints of Thick Ferritic Stainless Steel/16Mn Steel Plates
摘 要
采用电子束偏向16Mn钢侧的方法对40 mm厚铁素体不锈钢板与16Mn钢板进行电子束焊接,研究了焊接接头不同区域的显微组织和冲击韧性。结果表明:焊缝的显微组织主要为板条马氏体,随着距焊缝上表面距离的增大,焊缝的冲击韧性降低,断口呈现准解理和解理断裂特征。16Mn钢侧热影响区的的组织主要由针状铁素体和羽毛状上贝氏体组成,最大冲击吸收功为113 J,冲击韧性最好,断裂类型为韧性和脆性混合断裂;铁素体不锈钢侧热影响区组织均主要由铁素体、马氏体和颗粒状碳化物组成,冲击吸收功在6~10 J之间,冲击韧性最差,断裂类型为脆性断裂,这与粗化的铁素体晶粒和脆性碳化物有关。

Abstract
Electron beam welding was carried out between 40 mm thick ferritic stainless steel plate and 16Mn steel plate by electron beam biased to the side of 16Mn steel, and the microstructure and impact toughness of different areas of the welded joints were investigated. The results show that the microstructure of the weld was mainly lath martensite; with increasing distance from the upper surface of the weld, the impact toughness of the weld decreased, and the fracture was characterized by quasi-cleavage and uncleavage. The microstructure of the heat affected zone at 16Mn steel side was mainly composed of acicular ferrite and feathery upper bainite; the maximum impact absorption energy was 113 J, and the impact toughness was the best; the fracture type was ductile and brittle mixed fracture. The microstructure of the heat affected zone at ferritic stainless steel side was mainly composed of ferrite, martensite and granular carbides; the impact absorption energy ranged from 6 J to 10 J, and the impact toughness was the worst; the fracture type was brittle fracture, which was related to the coarse ferrite grains and brittle carbides.
