| 摘 要： | 研究了焊接热输入和微合金元素铌对铁素体不锈钢TIG焊接头组织及性能的影响.实验结果表明,随着焊接热输入的增加,焊接热影响区的粗晶区和焊缝区中铁索体晶粒明显粗化,降低了焊接接头的强度和塑性.铁素体不锈钢中加入少量的铌元素,通过钉扎晶界和拖曳晶界移动的双重作用,阻碍了粗晶区和焊缝区中铁素体晶粒的长大,提高了焊接接头的强度和...

| Abstract: | The effects of weld heat input and trace element niobium on the microstructure and mechanical properties of TIG welded-joint of ferritic stainless steel were investigated.The results showed that the ferrite grains were obviously coarsened in the coarse zone within HAZ and weld zone with weld heat input increasing.The strength and ductility of the welded-joint were decreased.The ferrite grain growth in coarse zone and weld zone was hindered through the double effects of pinning up the grain boundaries and dr... |
