Preliminary Study of the Effect of Remanence on Changes of the Residual Magnetic Field during Tension

Maciej Roskosz, Jerzy Kwaśniewski, Rafał Bogacz

The development of the application of the residual magnetic field (RMF) (measured on the surface of the ferromagnetic object) as a diagnostic signal involved the analysis of the effect of initial remanence on changes of the RMF during tension. Test plate specimens made of steel P91 (X10CrMoVNb9-1) in various as-delivered states were subjected to increasing active tensile stress. The test results revealed the significant effect of the condition of microstructure and initial remanence on the process and the final values of the RMF
