英文摘要：

Magnetic Barkhausen Noise（MBN）technique is a Nondestructive Testing（NDT）method capable of detecting the microstructure transformation,stress concentration and damage in ferromagnetic material.It can be used to assess the fatigue damage,the variation of microstructure,and the stress statue for ferromagnetic structure at the early stage.The research of MBN technique at present is reviewed in this paper,including magnetic material testing on stress,analyzing the fatigue stage of magnetic material,analyzing the metallographic structure,testing the surface hardness value,evaluating the surface treatment quality,and the comparision with other NDT methods.The MBN equipments and the standards are introduced in this paper and meanwhile,the development tendency of MBN technique is indicated.
