摘要
对１５ＭｎＶＮ钢手工焊焊接接头的疲劳性能进行试验研究。测定了焊接接头不同区域的疲劳裂纹扩展速率，以及不同加载条件下焊接接头的疲劳强度；分析了焊接接头组织变化和应力比对其疲劳性能的影响。
The fatigue properties of welded joints for 15MnVN steel were studied experimentally and comprehensively to determine the fatigue crack growth rates in different zone of the welded joints. The measurements included the fatigue strength under several loading conditions. In addition, the effects of microstructure and stress ratio were analyzed.
