Abstract
The limitation of power plant steel components designed for high temperature operation is mainly related to microstructural degradation and associated creep damage. Electromagnetic (EM) sensors can be used to detect phase transformation during processing, microstructural alterations due to heat treatment or in-service thermal exposure and the presence of cracks in steel. EM sensors primarily detect changes in the near surface microstructure of steels, due to changes in relative permeability and/or electrical resistivity, and are therefore sensitive to the components surface condition. The results indicate that the effect of any magnetite present in the oxide on the EM signal is less than the experimental error in the measurements.
