Abstract

Techniques based on Magnetic Incremental Permeability (MIP) measurements help to elucidate the physical/mechanical properties, which are correlated with the magnetic properties of the material. In this work, the MIP method was applied for the evaluation of creep-induced microstructural changes in a high-chromium steel subjected to different creep test conditions, such as stress and temperature treatments. Precipitations in the creep samples and recrystallization were investigated via Scanning Electron Microscopy (SEM) and Electron Backscatter Diffraction (EBSD). The correlation between featured parameters in the MIP signature curve and the microstructural analysis of the creep samples was also investigated.
