1 前言 晶间贫铬引起奥氏体不锈钢的晶间腐蚀和沿晶应力腐蚀,导致有关材料特别是核电设施的失效,故迫切需要有一种快速、非破坏性的定量检测技术及仪器,用于现场监测及评价奥氏体不锈钢的晶间腐蚀敏感性。1978年,Clarke等首先将电化学动电位再活化法(EPR)用作沸水堆(BWR)核电站中304及304L不锈钢管晶间腐蚀敏感性的
1 Preface Poor intergranularity of chromium causes intergranular corrosion and intergranular stress corrosion of austenitic stainless steel, resulting in the failure of relevant materials, especially nuclear power facilities. Therefore, there is an urgent need for a rapid and non-destructive quantitative detection technique and apparatus for Site Monitoring and Evaluation of Intergranular Corrosion Sensitivity of Austenitic Stainless Steels. In 1978, Clarke et al. First used the electrochemical kinetic potentiodynamic reactivation (EPR) as the susceptibility to intergranular corrosion in 304 and 304L stainless steel tubes in BWR plants
