摘要
综述了核级碳钢、低合金钢、不锈钢发生动态应变时效(DSA)的反常特征、影响因素及机制,讨论了DSA与高温高压水环境因素的交互作用对核电材料环境致裂的可能影响。指出了当前研究中存在的问题及进一步的研究方向。
The paper summarized the anomalous deformation characteristics, influencing factors and mechanisms of dynamic strain aging (DSA) in nuclear-grade carbon steels, low alloy steels and austenitic stainless steels. The possible effects of the interaction between DSA and high temperature water on environmentally assisted cracking of structural materials used in nuclear power plants have been discussed. The coming possible research topics and directions are also proposed.
