摘要
利用单试样步增量法，得到２０ｇ 母材和焊缝试样循环应力应变曲线及性能参数，分析了焊缝组织结构对循环行为的影响．
Structure steel 20g is used as a welded material specimen to conduct low cycle fatique test,Cyclic stress strain properties of welded metal(WM) and base metal (BM)and the performance parameters are obtained by means of step adding loads method.The different microstructure between BM and WM is compared,and the effect of mechanic properties on cyclic stress strain behaviors is also given.
