摘要 简要介绍上海大学"核电站关键材料的基础问题研究"课题组关于690合金晶界工程(grain boundaryengineering,GBE)的研究情况.借助上海大学分析测试中心的先进材料分析测试设备,开展了一些有特色的工作.从显微组织的表征与控制的角度,研究材料微观结构对宏观性能的影响.简要介绍690合金晶界元素偏聚、晶界碳化物析出、晶界网络分布控制以及对耐腐蚀性能影响等方面的研究结果. Grain boundary engineering (GBE) issues of Alloy 690 are briefly summarized. The work was carried out by the research group "Fundamental Issues of the Key Structural Materials for Nuclear Power Plants" at Shanghai University. By using advanced material characterization techniques, the microstruetures were characterized to establish its relationship with the properties. This article presents the research findings in grain boundary segregation, carbide precipitation, grain boundary network control and its effect on the intergranular corrosion resistance
