Effects of creep damage, shot peening, and case hardening on magnetic Barkhausen noise analysis

The micromagnetic emissions, commonly known as Barkhausen noise, are very sensitive to variations in the microstructure and sub-surface stress states of magnetic materials. Steel pipelines at power plants often have creep damage due to microstructural changes in their service life. Early detection o...
