目前还没有可用的技术来监测在役(高温下)的电站钢部件的微观结构状况。电磁(EM)检测方法有可能为这一问题提供解决方案。对不同组织状态的发电钢(P9和T22)样品进行了测试，采用了主要和次要的B-H回路测量，并建立了电磁性能与材料性能(如维氏硬度)之间的关联。这些相关性将被用来开发一种现场可部署的工具，用于量化电站钢材的退化。
There are currently no techniques available to monitor the microstructural condition of power station steel components in-service (at elevated temperatures). Electromagnetic (EM) inspection methods have the potential to provide a solution to this problem. Tests have been carried out on power generation steel (P9 and T22) samples with different microstructural states using major and minor B-H loop measurements and correlations established between EM properties and material properties such as Vickers hardness. These correlations will be used to develop a field deployable tool for the quantification of degradation in power station steels.
