摘要: 

研究了压水堆核电站一回路主管道用Z3CN20.09M铸造奥氏体不锈钢中金属间相的析出行为. 利用Image-pro Plus 6.0 软件统计了时效处理后不锈钢中析出金属间相的数量,获得了金属间相的时间-温度-转变(TTT) 曲线. 结果显示, Z3CN20.09M中析出的金属间相为M23C6σ, 析出温度范围分别为600-900 ℃和600-840 ℃, 其中750 ℃时析出最快. 研究表明, M23C6首先在α/γ相界析出, 然后σ相在铁素体相内形成.M23C6σ相在Z3CN20.09M中固溶化的温度分别为900和850 ℃. 850 ℃时, M23C6相的析出量随时间延长先增多后减少.

Abstract

The precipitation behavior of the intermetallic phases in a Z3CN20.09M cast austenite stainless steel (CASS) which has been widely used in primary coolant pipes of nuclear power plants has been investigated. The content of the intermetallic phases precipitated in the CASS was calculated by using Image-pro Plus 6.0 software. And then a time-temperature-transformation (TTT) diagram for the intermetallic phases was got. The results showed that the M23C6 and σ phases were precipitated in the steel during 600-900 ℃ and 600-840 ℃ respectively. The fastest precipitation velocity for the intermetallic phases occurs at 750 ℃. Moreover, the M23C6 was found to precipitate first at ferrite/austenite phase boundaries,and then σ phase formed in ferrite. The solutionizing temperatures for the M23C6 and σ phases are 900 and 850 ℃ respectively. The volume fraction of the M23C6 in the specimen aged at 850 ℃increases with the increase of aging time first and then decreases.
