摘要：

It is shown how the position, size and growth rate of cracks lying below the surface can be measured with the aid of a Foerster probe. This method is suitable for materials which form a ferromagnetic phase as a result of martensitic deformation (certain austenitic steels), provided that the difference between the loading temperature and martensite temperature amounts to about 50 degree C.
