| Abstract: | Metal magnetic memory testing technique is a new technique in the field of non-destructive testing, which is very suitable for the diagnosis before ferromagnetic parts failure, and has great potential in the estimation of fatigue intensity and life especially. This paper introduces the conception of metal magnetic memory and the state-of-the-art-of the testing technique at home and abroad, and presents the features and development. It also summarizes the current progresses in research on the field of magnetic memory. |
