| 摘 要： | 对16Mn钢双面埋弧焊CT试样的焊缝、热影响区、母材及垂直焊缝方向的疲劳裂纹扩展速率进行了研究。结果表明,焊接接头的不同部位疲劳裂纹扩展速率不同,平均应力、焊接残余应力、金相组织对疲劳裂纹的扩展速率都有一定的影响。

| Abstract: | The fatigue cracks propagation rate in the welded seam, HAZ, base metal and vertical welded seam in CT specimens of submerged are welding joints of 16Mn steel are sdudied. The results shown that the different zones of butt joints have different fatigue crack propagation rate. The average load, welding residual stress and the microstructures influenced the propagating rate of fatigue crack. |
