| Abstract: | Failure of ferromagnetic structural members is always associated with fatigue.Evaluation of fatigue damage degree of ferromagnetic materials is very important in engineering field.Magnetic nondestructive testing plays an important role in fatigue damage evaluation of ferromagnetic materials.The basic principles,characteristics and applications of magnetic Barkhausen noise(MBN),magnetic acoustic emission(MAE),metal magnetic memory(MMM) methods were presented.The present problems of three magnetic nondestructive methods were summarized.The potential application and future development of the three new methods were expected. |
