摘要
综述了轻水堆核电站大型容器壳体与主管道连接部位中异种金属焊接接头应力腐蚀裂纹扩展行为的研究进展,阐述了国内外关于材料、应力、环境等多种因素对应力腐蚀裂纹扩展行为的影响,并对需要进一步研究的方向进行了展望。
Recent progress on stress corrosion cracking(SCC) crack growth behavior of dissimilar metal welds between reactor pressure vessel and reactor coolant piping is reviewed in this paper.The worldwide studies concerning the effect of materials, stress and environmental conditions on SCC crack growth behavior are described. Meanwhile, the direction of further research is also forecasted.
