摘要 综述了轻水堆(LWR)核电站焊接结构材料环境促进开裂(EAC)的研究现状,分析了环境、材料、应力等相关影响因素,讨论了几种主要高温高压水EAC机理及考虑EAC效应的设计模型,最后指出了核电焊接结构材料EAC研究面临的问题及进一步的研究方向。 The present state of the environmentally assisted cracking （EAC） of the welded structur al metallic materials for light water reactor （LWR） nuclear power plants was reviewed. Three fac tors affecting the EAC of the welded metallic materials were taken into account, including corro sive environments, susceptible materials and stresses. Several EAC mechanisms and EAC involved design models are discussed. The coming possible research topics and directions in this area are al so proposed.
