| Abstract: | The magnetic traces were observed on a bolt forging during magnetic particle testing.The magnetic traces were analyzed by metallographic observation,energy spectrum analysis and X-ray diffraction analysis.The magnetic traces were non-relevant indication of the magnetic permeability difference of the material caused by the microsegregation of the raw material. |
