核电站一回路主管道铸造奥氏体不锈钢热老化研究现状与展望

Research Status and Outlook on Thermal Aging of Cast Austenitic Stainless Steels Used in Primary Coolant Pipes of Nuclear Power Plant

从热老化机理、研究方法、取得的成果等方面综述了半个多世纪以来国内外关于压水堆核电站一回路主管道铸造奥氏体不锈钢热老化研究的状况,分析了目前热老化研究中存在的不足,在此基础上提出了今后一回路主管道铸造奥氏体不锈钢热老化研究的方向。

The research status on thermal aging of cast austenitic stainless steels used in primary coolant pipes of nuclear power plant in the past nearly fifty years including thermal aging mechanism, research methods, achievement got and so on is reviewed. The possible value works on the thermal aging of primary coolant pipes in the future will be suggested after analysis the current problems of thermal aging research on the steels.
