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 anomalous characteristics, influencing factors and mechanisms of dynamic strain aging (DSA) of nuclear grade carbon steel, low alloy steel and stainless steel were reviewed. The possible influence of the interaction between DSA and high temperature and high pressure water on the environmental cracking of nuclear power materials was discussed. Points out the problems existing in the current research and further research directions.
