Weld residual stress and fracture behavior of 316L electron beam weldments, which are of particular interest in power generation industry, were investigated in this work. Two butt-weld joints were manufactured in stainless steel 316L plates of 6 mm and 25.4 mm thicknesses. Three complementary methods were used to measure the three orthogonal components of the residual stress in the weld coupons, and fracture tests were conducted on single edge notched bending specimens extracted from different regions of the welds and parent metals.

AISI 316L 电子束焊缝断裂韧性和残余应力评估

在这项工作中研究了 316L 电子束焊件的焊接残余应力和断裂行为，这在发电行业特别受到关注。两个对焊接头采用 6 毫米和 25.4 毫米厚的 316L 不锈钢板制造。使用三种互补方法测量焊缝试样中残余应力的三个正交分量，并对从焊缝和母材的不同区域提取的单边缺口弯曲试样进行断裂试验。
