| Abstract: | Magnetic detecting technique is a new technique in the field of nondestructive detecting, which includes metal magnetic memory detecting technique and magnetic anisotropy detecting technique based on counter magnetostriction stress. It is very suitable for the diagnosis before ferromagnetic parts failure, and has great potential in the estimation of fatigue intensity and life especially. The fundamental conception, characters and the state of arts of magnetic detecting technique were introduced, current doubt and problems of magnetic detecting technique and its trend were analyzed. |
